EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:
where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:
where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:
To find the equation, we now apply the point-slope formula:
Therefore, we have that the equation of the line is:
That is the equation of the line.

Answer:
The squirrel maximum height (h) = 21.125 ft
Step-by-step explanation:
The objective of this question is to determine the squirrel's maximum height.
Given that:
h = -2t² + 9t + 11
Differentiating h with respect to t, we get;
At the time dh/dt = 0, the velocity is maximum
Thus;
-4t = -9
4t = 9
t = 9/4
t = 2.25 seconds
From;
h = -2t² + 9t + 11
h = - 2(2.25)² + 9(2.25) + 11
h = - 10.125 + 20.25 + 11
h = 21.125 ft
