# How do you find the slope of (3,4), (6,9)?

##### 1 Answer

A *slope* of a line connecting two points *tangent* of an angle from the positive direction of the X-axis counterclockwise to a line connecting these two points.

Together with a point

The opposite to our angle side

Therefore, the *tangent* of angle

In our case

Slope equals to

I recommend to mark on this graph all three points
