Answer:
slope = -2
Step-by-step explanation:
To find the slope, you can use the slope formula, .
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through.
So, in order to answer the question, we need two points from the line. To find these points, look at the x and y values of the table - they form points. Thus, (-2, 0) and (-1,-2) would be two points the line passes through. Use those x and y values and substitute them into the formula. Then, solve:
Thus, the slope is -2.
