Well, to find the slop regardless, you do (Y2 - Y1) Divided by (X2 - X1). It is the same thing when finding the slope of any line.
Ex: (4,5) and (8,6). What is the slope? (6 - 5) / (8 - 4) = 1/4 <--- Slope

Answer:
Your answer is x = 1
Step-by-step explanation:
First start by distributing 5 to everything in the parenthesis.
5 * 2x = 10x
5 * -8 = -40
What you're left with is 10x - 40 + 15 = -15
Next subtract 15 from both sides.
10x - 40 + 15 - 15
The 15's will cancel each other out on the left side.
-15 - 15 = -30
What you're left with is 10x - 40 = -30
Next add 40 to both sides.
10x - 40 + 40
The 40's will cancel each other out on the left side
-30 + 40 = 10
What you're left with is 10x = 10
Divide both sides by 10 to get x by itself.
10x / 10 = x
10 / 10 = 1
What you're left with is x = 1
