Answer:
4/5
Explanation:
The first point (-4, -7) lies in the third quadrant and the second one in the first quadrant. This tells us immediately that the slope is positive; y increases as x increases. The change in x is 4 - (-4), or 8; this is the 'run.' The change in y is 3 - (-7), or 10; this is the 'rise.'
Thus the slope of this line is m = rise/run = m = 8/10, or m = 4/5
