Step-by-step explanation:
Hey there!
The given slope is; 3. And passing through point (-7,8).
Now,
Using one point formula.
[tex](y - y1) = m(x - x1)[/tex]
Put all values to find equation.
[tex](y - 8) = 3(x + 7)[/tex]
Simplify them to get answer.
[tex](y - 8 )= 3x + 21[/tex]
[tex]3x - y + 21 + 8 = 0[/tex]
[tex]3x - y + 29 = 0[/tex]
Therefore the required equation is 3x-y+29=0.
Hope it helps...
