Slope is used to describe the steepness or incline of a straight line. A higher slope value indicates a steeper incline. The slope of a line can be found by dividing the rise by the run. The y–intercept is the y–value at which a line crosses the y–axis. The graphs of linear equations are straight lines.

The y–intercept is 3. From the y–intercept, move 1 unit up (rise) and 4 units left (run) to find another line coordinate. Draw a line to connect the points. A horizontal line has a slope of 0. A vertical line has no slope. A line with a positive slope resembles a line going uphill. A line with a negative slope resembles a line going downhill. 1 4 The slope–intercept form of a linear equation is: y m x + b = y–intercept slope -4 5 The rise is 5 The run is –4 Slope rise run = = 5 4 Graph: y = x + 3 1 4 y–intercept -5 -4 -3 -2 -1 1 1 2 3 4 5 2 3 4 5 -1 -2 -3 -4 -5 0 © Copyright NewPath Learning.
