Answer:

Slope: #-1#
Intercept: #7#

Explanation:

First, rearrange the equation to make #y# your subject.

#y=-x+7#

From the equation, you know that the coefficient of #x# is always your slope. So, in this equation #-1# is your slope.

From the equation you would also know that any number behind the #x# is always your #y#- intercept. So your #y#- intercept is #7#.
