Final answer:
The slope of the line passing through the points (-1,0) and (0,-7) is -7.
Step-by-step explanation:
To find the slope of a line passing through two points, we can use the formula: slope = (change in y)/(change in x). Using the points (-1,0) and (0,-7), the change in y is -7-0 = -7 and the change in x is 0-(-1) = 1. Therefore, the slope is (-7)/(1) = -7.
So, the correct answer is c) -7.
