Let the number of hours be x
Assume x > 1
Total cost = 30 + 20(x -1) = 30 + 20x - 20 = 10 + 20x
Step-by-step explanation:
Substitute where x=0, 1, 2, 3and y=0, 1,2,3
And plot in the graph by joining the points
Answer:
m(slope)=0
Step-by-step explanation:
To find slope given two points, use the formula m = y2 - y1/x2 - x1
(-10) - (-10)/(-3) - 5
0/-8
Anything being divided from 0, or divided by 0 is always 0, so the slope is 0.
Hope this helps.
