LINER FUNCTION AND SLOP ( PARALLEL AND PERPENDICULAR LINES)#2021 Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope-intercept form, (i.e. in the form y = MX + c, where m is the slope and c is the y-intercept). Next, we plot the y-intercept, and using the slope, we can determine the rise and the run of the required line and then be able to plot the next point from the y-intercept. Finally, we draw a straight line passing through the two plotted points. Alternatively, we can determine the x-intercept and the y-intercept of the standard form linear equation by substituting y = 0, then solve for x and substituting x = 0, then solve for y respectively. Recall that the x-intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0. After obtaining the values of the x-intercept and the y-intercept, we plot the points on the coordinate plane and then draw a line passing through the points.
