When graphing slope, it is important to remember y= mx+b (slope formula). m is the slope, b is the y- intercept, and x, y are the coordinates. Starting at the y- intercept, graph the slope (rise over run). For the first question, the slope is 1/2. From the y- intercept, move up the y- axis one, and move across the x- axis two. The numerator represents the rise, while the denominator represents the run.
The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

Answer:
18 + x or x + 18
Step-by-step explanation:
Hi there! I'm glad I was able to help you solve this math problem!
We are already given the number eighteen to start with, so this helps us a lot.
Since the word INCREASED means to add, and <u>we're increasing eighteen by x</u>, all you have to do is write it out to get your algebraic expression, as shown:
18 + x
You can also write the expression as x + 18! It doesn't matter what order you write it in.
