# Interpreting slope of regression line

Interpreting slope of regression line.

## Want to join the conversation?

• how do you find the slope if they do not give it to you?
• How do you interpret the slope when it's a fraction??
• So, first things first we need to know what slope is. Slope is the change in y/change in x; the same thing as rise/run.
Here is an example:
Lets say you have a equation that says y=1/4x+2. Its pretty simple from there. So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you move 4 spaces to the right and 1 space up.

Hope that helps!:)
