Answer: A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

Answer:
m+6m/7m
Step-by-step explanation:
A number is m.
Plus is addition.
6 times m is 6m.
When you put these together it is:
m+6m.
You can simplify it too, which is 7m.

Explanation:
First, subtract

Now, divide each segment by

to solve for
x
while keeping the system balanced. However, because we are multiplying or dividing inequalities by a negative number we must reverse the inequality operators:
