Plzzzz answer fasttttt

What is the equation of a line that passes through (7, 8) and has a slope of -3?

Answer 1

When you know the coordinates $(x_0,y_0)$ of a point belonging to a line and its slope $m$, you can write the equation as

$y-y_0=m(x-x_0)$

Plug your values $(x_0,y_0) = (7,8)$ and $m=-3$ to get

$y-8=-3(x-7)$

which you can expand to

$y = -3x+29$
