Hello there,
Well we are going to start off with the equation to find the slope based on the given points:
Now using the two given points we are going to plug in and solve:
=
= 
From this you know that
is the slope of the equation. However, to find the y-intercept we are going to use y = mx+ b and plug in one of the points to solve:
(-14) =
(-22) + b
(-14) = (-11) + b
-3 = b
That means that the y-intercept is at (0, -3). Lastly, we are just going to plug all this into the slope-intercept form:
y =
- 3
Hope I helped,

Step-by-step explanation:
diameter = r * 2 = 13 * 2 = 26 (diameter is double radius)
Circle area = π * r^2 = π * 169 ≈ 530.9
Answer:
i think the answer is town a will be 6, town b 5 town c is 4
Step-by-step explanation:
- first you gather information that you already know
- second you put each number with the correct town
- last you subtract the probability of the numbers like 2-town a 8 which 6
