The slope of a line can be found using the formula:
m = (change in y) / (change in x)
In this case, the change in x from (-8, -1) to (8, -1) is 8 - (-8) = 16, and the change in y is -1 - (-1) = 0.
Therefore, the slope is:
m = 0 / 16 = 0.
So, the slope is zero.
Determine whether the slope of (-8, -1) and (8, -1) is positive, negative, zero, or undefined.
