Answer:


Step-by-step explanation:
Given

Solving (a): Equation when it hits the ground.
This means that 
So, we have:


Solving (b): The value of t in (a)

Using quadratic formula, we have:

This gives:




Split

Which is true about the slope of the function y=4x+3?

The slope of the function y=4x+3 is 4; in equations like this one, the slope is simply the number before x.
The rise is 4, and the run is 1.
Remember, slope is also defined as "Rise/Run"
