Question

What is the equation of the line that passes through the points (-2, 1) and (1, 10)?
3x - y = -7
3x - y = -5
3x - y = 5
x + 3y = -5

Answer 1

I know the slope is 3. and i got y-1=3(x+2)

Answer 2

(slope-intercept form)

Answer 3

simply plugged the the x, y numbers and
i got 3x-y=-7
as following
3*-2 -1=-7 and
3*1-10=-7

Answer 4

Thank you so much!
