# How to Find the Slope Of a Line

Whether you're doing your math homework or trying to figure out how steep a mountain is, the slope of a line is simple to calculate and has many practical uses.

### Instructions

- Step 1:
**Graph the line whose slope you are measuring**Use graph paper to graph the line whose slope you are measuring. Draw the line on standard x-and y-axis. - Step 2:
**Select two points on the line**Select two points on the line. Calculate where each point falls on the x- and y-axis to determine the exact points. - TIP: Write these points as ordered pairs – two numbers inside parentheses. First the x point, and then the y.
- Step 3:
**Subtract the y-axis locations of the two points**Subtract the y-axis location of the first point from the y-axis location of the second point. The difference is called the "rise." - Step 4:
**Subtract the x-axis locations of the two points**Subtract the x-axis location of the first point from the x-axis location of the second point. This difference is called the "run." - TIP: Pay attention to negative and positive numbers. A negative slope means the line travels downward, while a positive slope means it rises.
- Step 5:
**Divide the rise by the run to find the slope**Divide the rise in the y-axis by the run in the x-axis to find the slope of your line, an exact measurement of just how steep it is. - FACT: Did you know? Mount Everest was named after Sir George Everest, the surveyor who used mathematical equations to calculate the location and height of the world's tallest mountain.
