What is the equation of the line that passes through the points (−2, 1) and (1, 10)?

Question

3x − y = −7
3x − y = −5
3x − y = 5
x + 3y = −5

Answer 1

the slope is 3, so the point-slope form is

y-1 = 3(x+2)
or
y-10 = 3(x-1)

Now just massage that into one of the choices.

Answer 2

idk how

Answer 3

y-1 = 3(x+2)
y-1 = 3x+6
y = 3x+7
-7 = 3x-y
3x-y = -7

Looks like (A) to me
