Afood packet is dropped from a helicopter and is modeled by the function f(x) = -16x2 + 14400. the graph below shows the height f(x), in feet, of the food packet at different times x, in seconds: use the graph to determine the reasonable domain of f(x) based on the context. 0 ≤ x ≤ 30 0 ≤ x ≤ 14400 -30 ≤ x ≤ 30 all real numbers

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
