Solve for 1 hour

A. 100/3 miles in 2/3 of an hour

B. 97 1/2 miles in 3/2 hours

A because 100/3 is miles a hour

Without graphing, we can tell that a solution is going to be (0,-1). This is because in slope intercept form, y=mx+b, the “b” is our “y intercept.”
What this means is: the point on the graph that the given line goes through when x=0. In this case, “b” is -1, so the line will go through (0,-1).
