Answer:
The slope is 1.
Step-by-step explanation:
First, we must find the slope of the current equation.
This is the number in front of the x.
Seeing as this is -x, or -1x, the slope of this line is -1
When finding the slope of a line perpendicular, you need to find the
So, in this case it is:
The minuses cancel out, leaving with 1 over 1 or 1/
So the slope of the line perpendicular is 1!
