The slope-intercept form of given equation is y = 1/2x + 5/2.
According to the statement
we have given that the equation y-3 = 1/2(x-1) and the passing points are (–9, –2) and (1, 3).
And we have to find the slope-intercept form of the equation
slope-intercept form is the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
So, According to this
y-3 = 1/2(x-1)
convert this into y = mx +b form then
y-3 = 1/2x -1/2
here m is 1/2 and b is -1/2.
Then
y-3 = 1/2x -1/2
Add three on both sides then
y = 1/2x + 5/2
So, The slope-intercept form of given equation is y = 1/2x + 5/2.

How many numbers from 100 to 999 have exactly one zero digit
Answer:
180.
Step-by-step explanation:
100 contains 2 zero digits.
101 - 109 have 9 numbers, 110 to 200 have 11 numbers
so for 101 to 200 its 20 numbers
Its also 20 for 201 to 300 and for all sets of 100 up to 900.
- that is 7 * 20 = 140 numbers
Finally from 901 to 999 we have 18.
Total = 20 + 140 + 18
= 2 + 20 + 140 + 18
= 180.

The area of the shaded region is 3.125π - 6. The correct option is E. 3.125π - 6
Calculating areaFrom the question, we are to determine the area of the shaded region
The area of the shaded region = Area of the semicircle - Area of the triangle
First, we will determine the diameter, d, of the semicircle
d² = 3² + 4² (Pythagorean theorem)
d² = 9 + 16
d² = 25
d = √25
d = 5
∴ Diameter of the semicircle is 5
Thus,
Radius, r = 5/2 = 2.5
Now,
Area of the shaded region = 1/2(π×2.5²) - 1/2(3×4)
Area of the shaded region = 1/2(π×6.25) - 1/2(12)
Area of the shaded region = 3.125π - 6
Hence, the area of the shaded region is 3.125π - 6. The correct option is E. 3.125π - 6

Step-by-step explanation:
9) we know that the segment across from the angle 48° is double the angle.
48 · 2 = 96
The segments around the circle should all add up to 360 so we add the two segments we know to find the unknown segment.
136 + 96 = 232
360 - 232 = 128
The answer for 9 is 128.
10)

180 - 141 = 39
39 * 2 = 78
The answer for question 10 is 78.

How to find the solution of quadratic equation
Herein we have a quadratic equation of the form a · m² + b · m + c = 0, whose solution set can be determined by the quadratic formula:
x = - [b / (2 · a)] ± [1 / (2 · a)] · √(b² - 4 · a · c) (1)
If we know that a = - 1, b = 12 and c = 0, then the solution set of the quadratic equation is:
x = - [12 / [2 · (- 1)]] ± [1 / [2 · (- 1)]] · √[12² - 4 · (- 1) · 0]
x = - 6 ± (1 / 2) · 12

According to your line of best fit, what is the arm span of a 74-inch-tall person?
The variable that you would have to plot on the y axis (height) is the dependent variable while the variable that is on the x axis (arm span) is the independent or the explanatory variable.
How to get the slope of the lineThe slope was gotten through the use of the points (37,39) and (19,25)
This gave the slope of 7/9. This tells us that height of the person got to be raised by 7/9 inches when arm span increases by 1 inch.
From the given model, a person that has the arm span of 66 would have the height of

Using it's concept, the probability that exactly two of the dice show a 1 and exactly two of the dice show a 2 is: 10/243.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
One of the six numbers is of 1, and also one out of six is 2. The other two trials can be any of the other 4 numbers, hence the probability for the six rolls has the following format:

What is the interquartile range of the set of data this box-and-whisker plot represents?
Answer:
3
Step-by-step explanation:
The interquartile range is where the 2nd and 5th dots are, on the opposite ends of the square, from 15-18.
Answer:
3
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile (Q₃) and the lower quartile (Q₁).
In a box plot:
The left edge of the box represents the lower quartile.The right edge of the box represents the upper quartile.From inspection of the given box plot:
lower quartile (Q₁) = 15upper quartile (Q₃) = 18Therefore:
IQR = Q₃ - Q₁
= 18 - 15
= 3
So the interquartile range of the given box plot is 3.
There is a balcony that forms part of a circle around a stage, and they need to put up a safety railing. How long of a railing do they need if the radius of the circle is 40 feet, and the arc takes up 45°? Use 3.14 for pi.
A sector is a part of a circle that is formed by two radii, and an arc. So that the length of the safety railing required is 31.4 feet.
A sector is a part of a circle that is formed by two radii, and an arc, thus forming a central angle.
Thus the required length of safety railing can be considered as the arc of the sector.
So that;
length of an arc = (θ / [tex]360^{o}[/tex]) * 2[tex]\pi[/tex]r
where θ is the measure of the central angle of the sector, and r is the radius of the sector.
From the given question, θ = 45°, and r = 40 feet.
So that,
length of the safety railing = (45° / [tex]360^{o}[/tex]) * 2 * 3.14 * 40
= 0.125 * 2* 3.14* 40
length of safety railing = 31.4
Therefore, the length of the safety railing required is 31.4 feet.
