Y=mx+b
x=number of newspapers
37.5 earned for 5 newspapers
37.5=5m+b
earned 75 and deliverd 20 newpapers
75=20m+b
we have
37.5=5m+b and
75=20m+b
multiply first equaiton by -1 and add to other equaiton
-37.5=-5m-b
<u>75=20m+b +</u>
37.5=15m+0b
37.5=15m
divide both sides by 15
2.5=m
sub back to find b
75=2.5(20)+b
75=50+b
minsu 50 both sides
25=b
y=2.5x+25 is lnear funtion
Answer:

Step-by-step explanation:
The midpoint of a segment is the average of the end point coordinates.
F = (C + L)/2
F = ((0, 0) + (12, -6))/2 = (0+12, 0-6)/2 = (6, -3)
The fire station coordinates are (6, -3).
