Answer:
-1.75 I apologize if that is not right but i am 99% sure
Step-by-step explanation:
When you add like terms on the right side you end up with 2x, then all you di is divide both sides by 2 and you end up with -1.75
In order to find the slope of the line, find two points that are on the line and use the equation: m=(y2-y1)/(x2-x1). The 2 points should be whole numbers.
I'm pretty sure the answer is 15p^8
