The slope and intercept can be read from an equation in the form $y=mx+b$

When you isolate $y$ , the slope is given by the $m$ term (the coefficient of $x$ ), and the $y$ intercept is given by the $b$ term.

Rearranging $3x+y=-2$ to isolate $y$ , we get

$y = -3x-2$

The slope is thus -3, and the intercept -2.

How do you find the slope and intercept of 3x + y = -23x + y = -2?
