    First, put the equation in standard form for the equation of a line which is y = mx + b where m is the slope and b is the y-intercept:

    3x - 2y = 12

    -2y = - 3x + 12

    y = 3/2x - 6

    We plug in 0 for x to find the y-intercept:

    y = 3/2 (0) - 6

    y = - 6

    Now we can see the the y-intercept must be (0, - 6).

    Now to find the x intercept, plug in 0 for y:

    0 = 3/2x - 6

    3/2x = 6

    x = 4

    So the x intercept is (4, 0).

    These intercepts are plotted in Figure 3.1 and the line 3x + 2y = 12 is drawn through them. Figure 3.2: Adding the graph of y = x + 1. The second equation y = x + 1 has slope-intercept form y = mx + b. Hence, the slope is m = 1 and the y-intercept is (0, 1).
