average rate of change is the slope. You can use the two points to calculate the slope, or just use the graph and count rise over run.
rise over run is down 3 and to the right 1 = = -3
Answer: C
Answer:
y=-7 +1.5p
Step-by-step explanation:
get y alone so
-2y=14-3p
divide the -2y so
y=-7 +1.5p
Answer:
The answer to this question is: No solution.
Answer: The first number line.
When you are substituting equations, all you are doing is plugging in variables. Lets do an example..something random but easy...
y = 2x - 3
4x + 2y = 10
So since 2x + 3 equals y we are going to plug in those numbers into the second equation.
4x + 2(2x - 3) = 10
Now we distribute
4x + 4x - 6 = 10
Combine like terms.
8x - 6 = 10
Add 6 to both sides.
8x = 16
Divide.
x = 2
And thats how you substitute equations.
I hope this helps love! :)
