Question

ismael started the day with an irrigation pipe 120 feet long he used the equation L=15s+120 to determine the total length of the pipe as new section pipe, s, wear welded on to the end. what is the slope of the line? What does the slope represent in the context of the problem?

Answer 1

> what is the slope of the line?

The standard form of the linear equation is:

y = m x + b

where m is the slope, in this case the slope is m = 15

 

> What does the slope represent in the context of the problem?

The slope is the ratio of L over s. Therefore this means that the slope represents the change in total length per change in the wear welded onto the end
