Answer:- Atlanta is the reference point in this scenario.
Explanation:-
A reference point is a stationary place in a scenario which is used for comparison to determine if something is in motion. An object is in motion if it changes position respective to a reference point.
From the given situation, the reference point is Atlanta because Atlanta is the starting point such that the distance and time are computed from that point.

Though we cannot exactly find PT, we can find it in terms of TQ.
Multiply the second equation by 7/6 to get 7TQ/6=7x-7/3. Subtracting 65/3 from both sides, we get 7TQ/6-65/3=7x-24. Since the right side is equal to PT, PT=7TQ/6-65/3.

Step-by-step explanation:
Use the function to find the coordinates of the endpoints. Find the slope between those points, then use point-slope form to write the equation. If you wish, you can simplify to slope-intercept form.
For example, #66:
f(2) = -4(2) + 1 = -7
f(5) = -4(5) + 1 = -19
So the endpoints of the secant line are (2, -7) and (5, -19). The slope between those lines is:
m = (-19 − (-7)) / (5 − 2)
m = -12 / 3
m = -4
The equation of the line in point-slope form is:
y − (-7) = -4 (x − 2)
y + 7 = -4 (x − 2)
Simplifying:
y + 7 = -4x + 8
y = -4x + 1
f(x) is a line, so unsurprisingly, the secant line connecting two points on that line has the same equation.
Let's try #68:
g(2) = (-1)² + 1 = 2
g(5) = (2)² + 1 = 5
So the endpoints of the secant line are (-1, 2) and (2, 5). The slope between those lines is:
m = (5 − 2) / (2 − (-1))
m = 3 / 3
m = 1
The equation of the line in point-slope form is:
y − 2 = 1 (x − (-1))
y − 2 = x + 1
Simplifying:
y = x + 3
