The equation of a straight line is usually written this way: (or y = mx + c in the UK see below). y = how far up.

Finding an equation of a line using the slope-intercept form of the equation works well when you are given the slope and y -intercept or when you read them off a graph.

Here you will learn about how to find the equation of a line, including y=mx+b, recognizing the slope and y- intercept of a straight line, and finding the equation of a line given the graph.

Examples with detailed solutions on finding the equation of a line from a graph are presented. Exercises with answers and parallel, perpendicular, horizontal and vertical lines are included.
