B
Establish the equation of the line in slope-intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (- 3, - 3 ) and (x₂, y₂) = (3, - 1) ← 2 points on the line
m = 
= 
= 
the y-intercept is (0 , - 2 ) ⇒ c = - 2
y = x - 2 ← equation of line
This is a strict inequality since the line is broken, hence
y > x - 2 → B

Answer:
<em>t = 5 seconds</em>
Step-by-step explanation:
We must solve the equation of movement of the ball as a function of time in seconds.
We must find how many seconds it takes until the ball touches the ground. When the ball touches the ground, the height b (t) = 0
Then we equate the equation to zero and solve for t.
Use the quadratic formula.
Where
We take the positive solution
<em>t = 5 seconds</em>
