I am not to sure but I would go for B. identity.
First question: 0
Second question: 0.94
Hey there!
The x-intercept is where the line crosses the x-axis. The x-axis is horizontal. It crosses the line three left from the origin, or (0,0). This is -3. The x-intercept is -3. The answer would be either B or C. The line never hits the y-axis, so the y-intercept is none. The answer is C.
I hope this helps!
Let x equal the number of months
Total cost=$30 + $50x
X=5 months
So total cost= 30+50(5)=$280
Average rate of change is slope. The equation for slope is m=(y2-y1)/(x2-x1). (x2, y2) will be (5, 1) and (x1, y1) will be (-1, 7). Plug in and solve:
(7-1)/(5--1)
6/6
1
Hope this helps!!
