This math tutorial shows the relationship of a slope to a straight line and how to write equations in point-slope or slope-intercept form.

Given two points, the slope and a point, or the slope and the y-intercept, the student will write linear equations in two variables.

This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

Watch how a graph is altered when key elements of the equation change. This lesson focuses on how to manipulate the equation of a line in slope intercept form to match the graphs provided deepening the understanding of both the slope and...
