B. (1,1)
C. (3,3)
D. (4,4)
I inputted the equation into desmos, a graphing calculator, and the attached image was my result
By analyzing the image, the correct answer is D. (4, 4)
So the cable installer charges 52.50 an hour. meaning you would multiply that by whatever amount of hours he will work. so 52.50 times 4.5 hours equals $236.25. Now he also charges an extra fee for the service, So we add 75 dollars onto that making it $311.25.
If you want it in formula form here you go
y represent total amount in the end and x equals amount of hours
y=52.50x + 75
y = 52.50(4.5) + 75
y = 236.25 + 75
y = 311.25
