Question 7:

Step-by-step explanation:</h2>
The way to solve these types of questions, also know as "<em>slope</em>" is solved in the format 
(y minus y over x minus x) which also can be known as 
(rise minus rise over rune minus run). To solve this you can choose any two sets of numbers (the top and the bottom of a chart is 1 set) and you use its numbers to find the slope. One important rule when solving for slope is to never write your answer in decimal form and rarely write your answer as a whole number always answer questions in fraction form!!!! Anyway, the y and the x are already given so no need to find those as well. Here's the solving of all questions:

4.</h2>
for this question I choose the number sets:
so, now the easy part, 24-32=-8
Next we solve the bottom, 3-4=-1
so we end up with 
and when we simplify it can be written as or just 8 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
<h2>
5.</h2>
Now, for the rest of the problems I wont explain the solving process.
60-100=-40
185-235=-50
<h2>
6.</h2>
12.5-25=-12.5
5-10=-5
or 2.5 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
<h2>
7.</h2>
4-5=-1
2-3=-1
or 1 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).
Hope this helped, please give mw brainiest I spent half an hour on this :D
-Thanks for your time.
