y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
y + 10 = -1⁴/₂₁x + 7¹/₇
- 10 - 10
y = -1⁴/₂₁x - 3¹/₇
First graph it
#1
Maximum height is the y coordinate of vertex
Max height
#2
Time is the x coordinate of vertex
#3

x intercepts are the solutions
Take it positive
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
