Answer:
Step-by-step explanation:
First you have to find the slope
M= y2-y1/ x2-x1.
6-4 / 8-7 = 2/1 or 2
Then you pick one set of coordinates and plug the information into the formula. It doesn't matter which set you use as long as you plug the information in correctly.
I will choose (6,4)
Slope intercept formula is y-y1 =m(x-x1)
Y-4=2(x-6)
Then you simplify.
Y-4=2x-12
+4. +4
Y=2x-8 is your solution.

Answer:
Yes, because the total will be 51.50.
Step-by-step explanation:
3.75x3+6.50x4+14.25=51.50
Answer:
Part 1:
or 
Part 2: 
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get
(since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:


Then in this case you turn y=f(x), but the system did it for you, so all you have to put is
.
For the second part you must replace x with 2 since you need to find f(2).

Your answer for part 2 is
.
