Answer :
m=slope
(2,8)=(x1,y1)
we can use the next formula in order to find the equation of the line
[tex](y-y1)=m(x-x1)[/tex][tex](y-8)=4(x-4)[/tex][tex](y-8)=4x-16[/tex][tex]y=4x-16+8[/tex]the equation of the line is
[tex]y=4x-8[/tex]m=slope
(2,8)=(x1,y1)
we can use the next formula in order to find the equation of the line
