Answer:
Use the equation y2 - y1 over x2 - x1.
Explanation:
In instances where they ask you to find the slope of an equation, they will either provide a graph or points on the line. If there are points, label them correctly as x1, x2, y1, and y2. Then, input it into the equation and solve for the slope.
Most times, it will be a fraction indicating rise of run - for instance, 1/2.
In the instance that a graph is provided, look at the slope, take a point that is plotted easily where you can simply see the x and y values, and calculate the rise over run to the next plotted value.
