Step-by-step explanation:
Given

Required
Find the slope

Subtract 2 from both sides


Open bracket


Take LCM



An equation has the form:

Where

By comparing:
and 

<em>So, the slope is 1/4</em>
Answer:
1. its substitution
2.
3. order of operations
4. variable
5. equation
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. p=q/2r
For this case we have the following equation:

Where,
t: time
v: initial speed
s: initial height
Substituting values we have:

By the time the ball hits the ground we have:

From here, we clear the value of time:
Using the quadratic equation we have:

Doing the calculations we have:

Discarding the negative root, we have that the time is:
Answer:
it takes the ball to hit the floor about:
1.15 seconds
