In this lesson, we learn how to graph a line using the slope-intercept method. The first step is to plot the y-intercept, which is the coordinate where the line crosses the y-axis. The slope, which is the coefficient of x, is then used to plot another point on the line. By connecting these points with a straight line, we can accurately graph the line. To ensure the line is graphed correctly, we can check any point on the line to make sure it satisfies the given equation.
