Question 428210
YOUR ANSWER:
E(-2, 2), F(5, 1)
I have tried this:
Y-2=(-1/7)(x-(-2)
1-2/5-(-2)=(-1/7)

MY COMMENT: Your last step is incorrect!

You found the slope: m =(1-2)/(5 +2) = -1/7

Then used the point-slope formula:
y -yo = m(x -xo) where (xo,yo)is the GIVEN point.Let choose (-2,2)
y - 2 = (-1/7)(x - (-2))
y -2 = (-1/7)x  - 2/7

y= (-1/7)x - 2/7 + 2
y = (-1/7)x - 2/7 + 14/7
y = (-1/7)x + 12/7

There you go!John10
