Answer:
-1
Explanation:
Given equation of line is:
x - y = 8
In order to find the slope of other line we have to convert the given equation in standard form
So,
-y = -x + 8
Multiplying the equation with -1
y = x - 8
The co-efficient of x is the slope of the line.
Here the co-efficient is 1 so the slop of line is 1.
We know that the producct of slopes of perpendicular lines is -1.
Let m2 be the slope of the other line then
1 * m2 = -1
m2 = -1
So the slope of line perpendicular to line x-y = 8 will be: -1 ..
