Answer:
(four being the slope)
Step-by-step explanation:
So lets use
ΔY/ΔX
or the y2-y1 over x2-x1
![\frac{-8+4}{-3+2}](https://tex.z-dn.net/?f=%5Cfrac%7B-8%2B4%7D%7B-3%2B2%7D)
![\frac{-4}{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%7D%7B-1%7D)
Therefore, the slope is 4
To get the answer we can use proportion
60% -----------90
50% -----------x
Crossmultiply now
50*90=60*x
4500=60x /:60 (divide both sides by 60)
4500:60=x
75=x - its the result
Answer:
The customer pay to the plumber be $148 .
