In mathematics, the y-intercepts are where the graph crosses the y-axis, the x point is zero and The x-intercepts are where the graph crosses the x-axis, the y point is zero.
Find the x- and y-intercepts of 3x + 4y = 12.
To x-intercept(s): y = 0 for the x-intercept(s), so 3x = 12, xintercept=4.
To y-intercept(s): x = 0 for the y-intercept(s), so 4y = 12, yintercept=3.
