Aparabolic lattice arch is 8 feet high at the vertex. at a height of 4 feet, the width of the lattice is 4 ft. how wide is the lattice arch at ground level?

3; 9 is 8 to -4

step-by-step explanation:

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. : )
