Answer: b) -5/2
Step 1: Positive/negative
An important part of determining slope is figuring out if the graph is positive or negative.
Positive- highest point of the graph is on the right side; values increase
Negative-highest point of the graph is on the left side; values decrease
In this case the highest point of the graph is on the left side and the values increase our slope will be negative
Step 2: Write slope equation
The equation for slope using a graph
is: rise/run
This means that from one point to another you have to see the distance up and down over left and right
Step 3: Solve
Looking at points (0,2) and (2,-3), I see that the distance is 5 (rise) and 2 (run)
This will make our slope 5/2. But, since we established that the graph is negative, it becomes -5/2
