QUICK HELP! ): 20 POINTS!

A group of friends goes Sky diving, using a parachute to fall in a straight line from (1,45) to (3,36). If they keep going in a straight line, at what coordinates will they land on the x-axis?

Answer 1

at x = 11

0 =-4.5X +49.5

x = 49.5/4.5

x = 11

Explanation:

x1 y1 x2 y2

1 45 3 36

(Y2-Y1) (36)-(45)= -9 ΔY -9

(X2-X1) (3)-(1)= 2 ΔX 2

slope= -4 1/2

B= 49 1/2

Y =-4.5X +49.5
