Answer:
Step-by-step explanation:
To calculate slopes use the equation rise / run.
So count how many boxes up and divide that number by the number of boxes across to find the slope.
Make sure that you are using exact point on the slope (where the dots are on the line) to make it easier to calculate.
Also start from the left-most dot (look at slope B example)
For example for the slope of A:
2 blocks up, 5 blocks to the right so the slope is 2/5
But for slope B, since the first dot is higher than the second dot:
5 blocks down (-5), 1 block right so the slope is -5/1 or just -5.
