Answer: y = 4x - 12

Step-by-step explanation:

The formula for finding equation of line given the slope and a point is given as :

[tex]y -y_{1}[/tex] = m ( [tex]x -x_{1}[/tex] )

m = 4

[tex]x_{1}[/tex]= 5

[tex]y_{1}[/tex]= 8

substituting into the formula , we have :

y - 8 = 4 (x - 5 )

y - 8 = 4x - 20

y = 4x - 20 + 8

y = 4x - 12
