Answer:

1

Explanation:

You want the slope of the line perpendicular to y = 9 -x.

The slope of the given line is the coefficient of x: -1.

Lines are perpendicular when one has a slope that is the opposite of the reciprocal of the slope of the other. The slope of the desired line is ...

m = -1/(-1) = 1

Any line perpendicular to y = 9 -x will have a slope of 1.
