In Example 4, change the + before 4x to −.

Data from Example 4

Find the slope and the y-intercept of the straight line for which the equation is 2y + 4x − 5 = 0. We write this equation in slope-intercept form:

Because the coefficient of x in this form is −2, the slope is −2. The constant on the right is 5/2, which means that the y-intercept is (0, 5/2). See Fig. 21.23.
