What is the definition of graph intercept?

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.

Does a parabola have to have an x-intercept?

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.

What is the slope and y-intercept and x-intercept of y equals -x plus 1?

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


What is the difference between the x- intercept and the y- intercept?

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


What is the slope of a line that has a y-intercept but no x-intercept?

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.


What is the intercept for y equals x plus 10?

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


What is the x intercept and the y intercept of x-9y equals 18?

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


What is the x intercept of 2xx?

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


In slope what is the X-intercept?

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


What is the x-intercept and y-intercept of the equation y equals -x-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)
