Question 428210: Indicate in standard form the equation of the line passing through the given points.
E(-2, 2), F(5, 1)
I have tryed this:
Y-2=(-1/7)(x-(-2)
1-2/5-(-2)=(-1/7)

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
