An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.

Is the point symmetrical to the y-intercept the same thing as the x-intercept?

No, it is not. The y-intercept is the point where a function is evaluated as x=0. The point symmetrical to that is the one the same distance from the origin along the y-axis. For example, in the function y = 3x + 2, the y=intercept is (0,2) and the point symmetrical to that is (0,-2) Also, the x-intercept is when y=0 (solving for x) ■


Is it possible for a line to not have a y intercept?

Yes, but only of the line is vertical. (It would then be written as x = a, where a is a constant. For example, the line x = 8 does not have a y-intercept. All lines in the form y = mx+b will have a y-intercept.)


What is the slope and y intercept formula?

The slope intercept formula is y=mx + b in which m is the coefficent by x, x is the slope, and b is the y-intercept which is why it is called y-intercpet or slope-intercept. An example: y=3x + 7. Here your slope is three and y-intercept 7.


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 if a graph has no x- or y-intercept Will what you say about the line always be true in that situation?

It could be a line segment within a quadrant that does not have an x or y intercept Or a graph with a restricted domain, for example, y = 1/x where x>0

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
