Answer:
1 23/30
Step-by-step explanation:
you convet the mixed numbers into improper fractions then find the lowest common factor and combine :)
-8+4x=-20x-25+7x
4x+20x-7x=-25+8
17x=-17 /17
x=-1
The equation with (x) in dogs and (y) in dollars is 
First, you must set up your equation.

Then, you must add like terms to simplify the equation

Slope: (y2-y1)/(x2-x1)
(-3+2)/(-1+1) = -1/0 = undefined
The slope is undefined
