Answer:
It will cost $36.38 to travel 8.9 miles.
Step-by-step explanation:
In order to get how much it will cost to travel 8.9 miles, you need to first set up a linear equation (in slope-intercept form, which is 
). You can do this with what the problem has given us. Since there's a flat fee of $3, that is the y-intercept or the 
slope-intercept form. Then there is $3.75 added for every additional mile traveled, making it the slope or the 
in slope-intercept form. That makes the equation look like:
The 
in that equation represents how far you traveled. Therefore in order to find out 8.9 miles, plug in 8.9 for .
Simply solve the equation and you will have how much it will cost to travel 8.9 miles.
Now add the like terms:
Since it needs to be rounded to the nearest cent, you will round to the nearest tenth:
Therefore, it will cost $36.38 to travel 8.9 miles.

Quadratic Formula
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3
