The equation of the line through point AxA yA A x A y A with the slope m is determined by the formula y yA mx xA y y A m x x A Define What is the Slope of Line. The other format for straight-line equations is called the point-slope form. What is the equation of the line in point-slope form.
When graphing a linear equation the whole idea is to take pairs of xs and ys and plot them on the graph.
Count units to determine the slope ratio. One way is using the slope-intercept formula y mx b And the other way is by using the point-slope formula Example of Finding The Equation Of A Line Given The Slope And A Point Example 1. Substitute the slope for m in the slope intercept form of the equation. Y 4 12 x 4 y 4 12 x 4 y 0 2 x - 4 y 4 2 x 0 search.
