Answer:
-7/6
Step-by-step explanation:
I have plotted 8,10 and 2,17 on a grid and connected them with a line to help visualize the slope of the line we are trying to find.
The answer can also be written as a decimal as shown below, but it is neater to use the fraction.
If you draw out a coordinate plane you will see that they , on their Y access, are both nine witch means that they a horizontal line so all you have to do is subtract the x access witch is 3.
hope this helped
