Hello!
Find the coordinate where x = -1:
At x = -1, y = 1, so the coordinate is (-1, 1).
Find the coordinate where x = 2:
At x = 2, y = -2, so the coordinate is (2, -2).
Find the rate of change between the points using the slope formula:

Plug in the coordinates above:

Simplify:
Thus, the rate of change between the points is -1.
Answer:
x = 1/8 = 0.125
Step-by-step explanation: Add 1 to both sides of the equation :
8x = 1
Divide both sides of the equation by 8:
x = 1/8 = 0.125
Answer: There are no solutions.
Step-by-step explanation: So the way you do this is by subtracting 9p from both sides, which gets you:
8 = -7
Since 8 is not equal to -7, there is no solution to this equation.
