Question

Indicate in standard form the equation of the line passing through the given points.

E(-2, 2), F(5, 1)

Answer 1

Have you considered calculating the slope of the line connecting the two points?

Answer 2

yes @tkhunny i got 1x+y=3 and it was wrong

Answer 3

@thomaster

Answer 4

E(-2, 2), F(5, 1)

Well, you made some error along the way. Keep trying until you don't make errors.

m = (2-1)/(-2-5) = 1/(-7) = -1/7

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

7y - 14 = -x - 2

x + 7y - 12 = 0
x + 7y = 12

One of those.
