George hiked from the top of a hill to The Valley floor. The elevation at the top of the hill is 127 1/2 feet above sea level. The Valley floor is 52 1/2 feet below sea level.

George stopped at a rest stop that is at an elevation exactly halfway between the top of the hill and The Valley floor.

What is the elevation in feet of the rest stop?

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
