HELP DUE IN 2 HOURSSS

1.05 miles per hour

Step-by-step explanation:

m = y2 - y1/ x2 - x1 (It doesn't matter which you choose to be y2 and y1, just make it consistent)

m = 4.2 - 2.1/ 4 - 2

m = 2.1 / 2

m = 1.05

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
