In your own words explain how being able to find the vertex of a pro Avila can help you in real life can you think of other situations that you can model with vertex form?

Any projectile that is under the rules of gravity can be modeled by a parabola!

Picture a football player kicking the ball up: it will follow a parabolic orbit, and the vertex is the highest point it will reach.

Picture a roller coaster: it will most likely follow a parabolic orbit, with the vertex being that scary moment on the top of the roller coaster track.:)

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. : )
