The rate of change is 10.5/3
It cost $3.50 per yard
The total cost for 8 yards is $28
If the total cost of buying fabric is $42 the amount of yards that were bought would be 12
Answer:
B
Step-by-step explanation:
We can graph the line using the y and x-intercepts. To find the y-intercept, we substitute x = 0 into y = -2x - 2 so the y-intercept is (0, -2). To find the x-intercept, we substitute y = 0 into y = -2x - 2 so the x-intercept is (-1, 0). The line that goes through both of these points is line B.
