7k + 4 is the simplified version
The maximum height is the y-coordinate of the vertex (x,y) of the parabola.
First find the x-coordinate using the formula:
Now plug the value into the equation and find the y-coordinate:
The maximum height is 36 feet.
Answer:
find gradient/slope
-8-(-5) / -2-(-1) = -3/-1
= 3
y=3x+c
perpendicular line formula
m1(m2)= -1
(sub in the gradient before)
3(m2)= -1
m2= -1/3 ( perpendicular line gradient)
y=-1/3x+c
(sub in the coordinate)
-5=-1/3(-3/2)+c
-5=1/2+c
-11/2=c (y intercept)
answer: y= -1/3x - 11/2
