In the first line of Example 8, if + is changed to −, what changes result in the example?

Data from Example 8

Find the slope and the y-intercept of the line 2x + 3y = 4. We must first write the equation in slope-intercept form. Solving for y, we have

Therefore, the slope is −2/3, and the y-intercept is the point (0, 4/3)See Fig. 5.10.
