Step-by-step explanation:
13.
Given


Required
Determine the distance between M and S
Distance (D) is calculated using:

Where








<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.

Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is

<em>i.e. we add the units to the y coordinate of P.</em>
Answer:
D
Step-by-step explanation:
These triangles would be Slided or Translated across a coordinate plane not reflected. :)
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
