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
