Answer:
19. y=5x+-1
20. y=-2.5x+4
Step-by-step explanation:
19: 9-4=5
-1+5=4 so m=5
b=-1
so y=5x+-1
20: -1-1.5=-2.5
4+-2.5=1.5
so m=-2.5
b=4
so y= -2.5x+4

First student has a 1 minute head start at .20 miles per minute.
This is a distance of .2 miles.
The second student has to make up this distance by running at .25 miles per minute. This produces a net gain on the first student by
(.25 -.20) = .05 miles per minute.
So how long does it take to run .20 miles at .05 miles per hour?
.2 miles / .05 miles per minute = 4 minutes.
1 mile = 1,760 yards
2 miles = 3,520 yards.
plus 20 more = <u>3,540 yards</u>
