Answer:
rise over run or rise/run
Step-by-step explanation:
rise over run is just how many boxes you rise until you are at level with the second point. The run part is how many do you have to go over to get to the second point. For example, in the picture you would rise 5 and run 3.
So the slope would be 5/3x.
The slope is positive if the line looks like this / and the slope is negative if it looks like this \.
Hope this helps ya!
Answer:
x= -7
Step-by-step explanation:
You need to first add 5 to the -5. Even though the - is a subtraction sign, you can still count it as a subtraction sign. In order to balance it out again, so you add the 5 to the 16. 16+5=21, so the equation would be -3x=21. To get x by itself, you divide by -3. So, -3x/-3 and 21/-3. That gets rid of the -3, and you get a -7 as an answer.
