Answer:

Step-by-step explanation:

Plot any tow points on the line and find the slope

(-1 , 3)  ; ( -2 , 1)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]= \frac{1-3}{-2-[-1]}\\\\= \frac{-2}{-2+1}\\\\=\frac{-2}{-1}\\\\=2[/tex]

m = 2 ; (-1 , 3)

 y - y1 = m(x - x1)

y - 3 = 2*(x - [-1])

y - 3 = 2*(x + 1)

y -3 = 2*x + 2*1

y -3 = 2x + 2

   y = 2x + 2 + 3

  y = 2x + 5

Slope = 2

y-intercept = 5
