The slope of a graph gives you valuable information about the relationship between the two variables that were graphed. Essentially, the slope describes how much the "y" variable (on the vertical axis) moves per unit change in the "x" variable (the horizontal axis).
If 1 Point and the Slope are Known. X 1 =. Y 1 =. distance (d) =. slope (m) =. OR angle of incline (θ) = °. Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m.
