Formula: Slope = The change in y divided by the change in x. So let's say that you were trying to find the slope of a line based off the points (9, 5) and (5, 3).

Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.

In an equation in slope-intercept form (y=mx+b) the slope is m and the y-intercept is b. We can also rewrite certain equations to look more like slope-intercept form. For example, y=x can be rewritten as …

Learn about the slope of a line and its calculation through engaging video lessons on Khan Academy.

To find the formula for the linear equation representing the trend line, you first need to determine the slope and y-intercept. The slope is calculated using the formula: Slope = change in y / change in x = …

Formula: Slope = The change in y divided by the change in x. So let's say that you were trying to find the slope of a line based off the points (9, 5) and (5, 3).

Explore slope-intercept form of linear equations with Khan Academy's interactive lessons and practice exercises.

Find the slope of the line that goes through the two points that are given to you.

The slope specifies both the direction and steepness of the line. If we have a zig-zag graph or curved graph, then we can use the slope formula to find the average rate of change in the graph.
