The slope is -11 and the y-intercept is -22.

Explanation:

x+y=-2x+y=2

To convert the linear equation in standard form to slope-intercept form, y=mx+by=mx+b, where mm is the slope and bb is the y-intercept, solve the standard equation for yy.

Subtract xx from both sides of the equation.

y=-2-xy=2x

Rearrange the right hand side.

y=-x-2y=x2

The slope is -11 and the y-intercept is -22.
