Answer: y=3x--5
Step-by-step explanation: First simplify by distribution and lie terms to get:
y=3x-5
3 is your slope which means every time your y goes up three your x goes across one.
-5 is your y-intercept which means (0,-5) goes through your line
Just replace a with 4 and b with 2 and your equation looks like
3.14 (4×2+4×2)
solve within the parenthesis first
3.14 (8+8)
3.14 (16) =50.24
The answer is $8.75. You have to find what one costs which is 1.25 so if you have 7. 1.25 times 7 is $8.75
