This graph shows how fast a commercial airliner travels in flight What is the meaning of the point with an xcoordinate of 2?

the answer is b. in two minutes, the airplane travels 18 miles

Step-by-step explanation:

A PE X

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).
