For x and y
When you subtract 2 from x, you will subtract 7 from y
60+3=63
10x6+3=63
7x9=63
20x3+3=63
PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.
14.35, square root 3296 and then multiply by 4.
First, let’s find how much she spent on monthly operating costs.
5250-4500=750
Then, because all 5 months have been consistent, we can divide by 5
750/5=150
The answer is C
