Answer:
45 dollars for going over 2GB
Step-by-step explanation:
If he pays 25 dollars every month and he goes over 2 GB then he’ll have to pay 20 dollars extra since every GB over cost 10 dollars. The equation is 25+10+10 which equals 45.
1) Just simplify the equation first:
y - 9 = (2/5)(x - 5)
y - 9 = 2x/5 - 2
2) Transfer everything to the left with opposite sign:
-2x/5 + y - 9 + 2 = 0
-2x/5 + y - 7 = 0
3) Get rid of rational numbers by multiplying:
-2x/5 + y - 7 = 0 |*5
-2x + 5y - 35 = 0
That's the answer. Good luck!
