Answer:

2x +5y = -15

Step-by-step explanation:

We need to find the slope

m = (y2-y1)/(x2-x1)

= (-7--1)/(10- -5)

= (-7+1)/(10+5)

-6/15

-2/5

The point slope form

Y+7= -2/5 (x - 10).

Distribute

y + 7 = -2/5x + 4

Add 2/5 x to each side

2/5x +y +7 = 4

Subtract 7 from each side

2/5x +y = -3

Multiply each side by 5

5(2/5x +y) = -3*5

2x +5y = -15

This is standard form Ax + By = C where A is a positive integer

tigry1 [53]

C = $\pi$ r
9.5 = 2 $\pi$ r
$\pi$ r = 4.75
r = 1.511971959
The number above should be rounded to the nearest 2 decimal places, so the answer is 1.51.
