Answer:
-4
Step-by-step explanation:
The point (x, y) = (0, 0) is on the line, so it represents a <em>proportional relation</em>. Any ratio of y to x will be the slope. The choice that makes this computation easiest is ...
x = 1, y = -4
y/x = -4/1 = -4
The slope of the line is -4.
For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:

Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:

Rewriting we have:
Answer:
The scale factor of dilation is given by:
To determine how long it takes to consume, simply take 15,300 watt hours and divide it by the initial rate of 3600 watt hours per day.
21 and -4, because -4x21 = -84, and 21+-4 (– 4) = 17
