If you use the x-intercept and y-intercept method, you get x-intercept (4, 0) and y-intercept (0, 3). If you use the slope-intercept method, the equation, when written in y = mx + b form becomes y= - 34 x + 3 Because the original inequality is <, the boundary line will be a dashed line. Look at Figure 2-11. Figure 2-11 The boundary is dashed. y 4 3 2 1 −3 −2 −1 1 2 3 −1 x 4 3x + 4y = 12 −2 −3 Now, select a point not on the boundary, say (0, 0). Substitute this into the original inequality: 3x + 4y < 12 ?

It will always have an x-coordinate of zero. A vertical line that is not the y-axis will have no y-intercept. One way to graph a linear equation is to find solutions by giving a value to one variable and solving the resulting equation for the other variable. A minimum of two points is necessary to graph a linear equation. Example 6: Draw the graph of 2x + 3y = 12 by finding two random points.
