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
