Answer:y = 2x − -3 find the y and x and then identify if its zero slope or undefined.
Step-by-step explanation:
Water bill of Simons in the month of August = $48
Percentage of bill that was lower in the month of September = 15%
then
Amount of bill that was lower in the month of September = (15/100) * 48
= 720/100 dollars
= 7.2 dollars
So
The bill for the month of September = (48 - 7.2) dollars
= 40.8 dollars
So Simon will have to pay $40.8 as the water bill for the month of September. I hope the procedure is clear enough for you to understand.
We know:
substitute a = -3; b = 7; c = -15
