to find the equation you need any two points on the line
let us pick (0,-2) and (1,1)
we can find the slope
[tex]m = slope = \frac{ - 2 - 1}{0 - 1} = \frac{ - 3}{ - 1} = 3[/tex]
using the point-slope equation
(y-y1)=m(x-x1) so choosing either of the points i will pick (1,1)
y-1=3(x-1)
y-1=3x-3
y=3x-2 which is b
