If y = 5x - 2 were changed to y = x - 2, how would the graph of the new function compare with the first one?

Every x coordinate of the first graph would be a multiple of 5. Example when x is 2, y = 8. The (x,y) coordinates for the first graph becomes (10,8). The second graph has a y value of 0 when x is 2. So its coordinate becomes (2,0). We see a trend here, the x coordinate of the second graph is 1/5 the x coordinate of the first graph.

Yes

Step-by-step explanation:

If he makes 2 stops each for ten minutes he still has 3 hours and 40 minutes left to make it to where he needs to be. If he still is going the same speed he will most definitely make it on time.
