Answer:
y=-3/4x+4
Step-by-step explanation:
Equation Format:

where m = slope & c = y-intercept
Hence:
7=-3/4(-4)+c
7=3+c
c=4
y=-3/4x+4

<h2>
Hello!</h2>
The answer is:
The ball will hit the ground after 
<h2>
Why?</h2>
Since we are given a quadratic function, we can calculate the roots (zeroes) using the quadratic formula. We must take into consideration that we are talking about time, it means that we should only consider positive values.
So,

We are given the function:

Where,

Then, substituting it into the quadratic equation, we have:

Since negative time does not exists, the ball will hit the ground after:

Have a nice day!
