The intercept of a graph is the point where is crosses one of the coordinate axes. The x intercept is where it crosses the x axis, the y intercept where it crosses the y axis. If the graph is given as y equals a function of x, it is usually easier to find the y intercept, because that is where x is 0. You just plug in 0 for x and evaluate. To find the x intercept, you plug in 0 for y and then you have to solve an equation for x. This is fairly easy if it is a linear equation (the graph is a straight line), somewhat harder for a quadratic (a parabola). But anyway you only asked for a definition, and I have given it.

X-intercept=3 y-intercept=-2

A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.

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)

2y + x = 12At the x-intercept, y=0:x = 12At the y-intercept, x=0:2y = 12y = 6

No, a parabola does not have to have an x-intercept. ex. -2(x-2)^2 - 4 is a parabola that has no x-intercept.

X-intercept=3 y-intercept=-2

Slope is -1 y-intercept is 1 x-intercept is 1

The y-intercept is where the line crosses the y-axis, and the x-intercept is where the line cross the x-axis

A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.

y - intercept = 10x - intercept = -10y- intercept: x = 0y = x + 10y = 0 + 10y = 10x - intercept: y = 0y = x + 100 = x + 10x + 10 = 0x = -10

x - 9y = 18At the x-intercept, y=0 :x = 18At the y-intercept, x=0 :-9y = 18-y = 2y = -2

The x-intercept is 0. To find the x-intercept of any equation, simply make y = 0 and then solve for x.

The x-intercept is the point where the graph touches the x-axis.

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)
