You combine like terms like 8y+13y which gives you 21y and don't forget the -5x so your simplified equation would end up being A. 21 - 5x
(I'm guessing you mean ton)
10 ton = 20,000 pounds
Answer:

Step-by-step explanation:
Finding the slope (m) of the line the following points in the line, (0, 0) and (2, 20):

y-intercept (b) is 0. The line intercepts the y-axis at 0. Thus, b = 0.
Substitute m = 10 and b = 0 in 
The equation in slope-intercept form for the graph would be:
