Question

Find the point-slope equation for

the line that passes through the
points (-2,-20) and (9, 79). Use
the first point in your equation.​

Answer 1

y+20=9(x+2)

Explanation:

y-y1=m(x-x1)

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

m=(79-(-20))/(9-(-2))

m=(79+20)/(9+2)

m=99/11

m=9

y-(-20)=9(x-(-2))

y+20=9(x+2)
