8. Find the slope-intercept form for the equation of the line which passes through the point (-9,-1) and
the origin.

Step-by-step explanation:

We are given that the lines passes trough the points (-9, -1) and (0,0).

(0,0) is the origin.

Slope is:

The slope is one-ninth.

Since the lines passes at the origin, it's y-intercept is 'zero'. We do not write zeros in slope-intercept equations, to the equation of the line should be:

They'd be MOST affected by whichever answer choice would make climate change there even worse because in South Africa, the climate is already really bad.
Based on that I'd say THE ANSWER IS
C) the spread of the Kalahari Desert
