Answer: -3
Step by Step Explanation: This type of equation is called slope-intercept form, y=mx+b; the slope is m, so the slope is -3
I think X is 2. But I am not sure, cuz I don’t know what you teacher is really asking you to do.
Answer:

Step-by-step explanation:
Assuming that the patio is a rectangle, we have

Where
is the length and
is the width.
Now let's assume that the length of the patio is double than the width.

So, the equation that represents this problem is

Answer:
"Multiply the previous value by 2"
Step-by-step explanation:
Let's check the first 2 terms for all the answer choices.
1. Add
to the previous value:

Doesn't match.
2. Subtract
from the previous value:

Doesn't match.
3. Divide the previous value by 2:

Doesn't match.
4. Multiply the previous value by 2:

DOES WORK!
Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
This is equal to -3-5/7, or (-3*7)/7-5/7, or -21/7-5/7, or -26/7.
