The answer is -1. You can multiply 3 by -2 which is -6. Then y is, obviously, 1. 3z would equal -6 because 3 times -2 is -6. The final equation is: -6-1-(-6. -6 minus 1 1is -7. Then -7 minus -6 is -1 because a negative minus a negative will be a negative.

Answer:

The last graph best represents the story

Step-by-step explanation:

So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.

When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.

After resting she still continued her journey to school.

This part also has a positive slope.
