Need help solving this problem

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 .

0 = x+y -2

Step-by-step explanation:

The general form of a line is 0 = Ax + By + C  where A is a positive integer

First write it in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

The slope is

m = (y2-y1)/(x2-x1)  (2,0) and (0,2)

   = (2-0)/(0-2)

   = 2/-2

   = -1

and the y intercept is 2

y = -1x +2

Subtract y from each side

0 = -x -y +2

Multiply by -1

0 = x+y -2
