Y = -x +3
x+y = 17

Are these parallel?

Answer:

Yes

Explanation:

The equations need to be in slope intercept form. The first equation is but the second one isn't. Solve the second equation for y to put it in slope intercept form.

x + y = 17

x - x + y = 17 - x

y = -x + 17

To determine if they are parallel the slopes need to be the same.

y = -1x + 3

y = -1x +17

The slope are both -1, so they are parallel
