solve the x and you find the y
To find the y intercept put zero in for x and solve. To find the x intercept put zero in for y and solve. (0,8) and (-8,0)
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
To find the x-intercept, plug 0 in for y: 0 = -x-1, so x = -1. To find the y-intercept, plug zero in for x: y=-0-1, so y = -1 The x-intercept is (0,-1) and the y-intercept is (-1,0)
Normally, the y-intercept would be after the x term, but because there is no x term the y-intercept is 0.
