Question

A road construction crew has planned a project to repave a highway with new asphalt.

● 2 miles of the highway had already been paved during a previous project.
● 5 miles of the highway will be paved each week during this project.

Which graph best represents the relationship between y, the number of miles of highway paved, and x, the number of weeks the crew will work, for both projects?

Answer 1

So at 0 weeks 2 miles had been done
So graph starts at (0,2) somewhere between 0 and 5
Now, at 2 weeks 10 miles has been done and 2 miles was the initial paved
Thus at 2 weeks we see that 12 miles has been paved which should be a little above 10
Among the options b seems the most appropriate to me according to above information
