First, we'll find the slope of the new line. The first line has a slope of
. Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by
) to get
for the new slope.
Then, we'll use the point-slope form to make the new equation, where
is the slope and
is a point on the line:

Answer:
wut.
Step-by-step explanation:
For a you would just have to add all the velocity up and divide by 5. For b its -15 the ball is going down.
