Answer:
y=4x+7
Step-by-step explanation:
4x+y=7
Isolate one of the variables
4x-4x+y=7+4x
y=7+4x
slope is 4 (Up 4, Right 1)
y-intercept is (0,7)
Answer:
multiple y and get through the point
Nickels = x
dimes = x + 4
quarters = x
Value of coins:
nickel = 5 cents
dime = 10 cents
quarter = 25 cents
5x + 10(x + 4) + 25x = 3.20
5x + 10x + 40 + 25x = 320
40x = 320 - 40
40x = 280
x = 280/40
x = 7
There are 7 quarters, 7 nickels and 11 dimes.
