Slope is a measure of how steep a line is on a coordinate plane. You can find the slope by comparing the rise (vertical change) to the run (horizontal change). Slope is always written as a ratio, such as 'rise over run' or '3/4'.
Finding Slope on a Coordinate Plane

Slope: The steepness of a line on a coordinate plane, or the ratio of the vertical change to the horizontal change between two points on the line. Coordinate Plane: A two-dimensional plane that is divided into four quadrants and is used to locate points by their x- and y-coordinates. Intercepts: The points at which a line crosses the x-axis and the y-axis of a coordinate plane.

The slope of a line on a coordinate plane is the ratio of the vertical change between two points to the horizontal change between the same two points. The slope of a line can also be found by counting the number of “units” up or down and then counting the number of “units” left or right. The slope of a line can also be used to calculate the distance between two points on the coordinate plane.
