For a line, this is the x-intercept. For a polynomial, these points are the roots or solutions of the polynomial at which y=0.

What is the point where the graph of a line crosses the horizontal axis?
y-intercept
What is a root in a polynomial graph?
A root is the value of the variable (usually, x) for which the polynomial is zero. Equivalently, a root is an x-value at which the graph crosses the x-axis.
What does it mean for a function when the graph of the derivative crosses the x-axis?
This means that the function has reached a local maximum or minimum. Since the graph of the derivative crosses the x-axis, then this means the derivative is zero at the point of intersection. When a derivative is equal to zero then the function has reached a "flat" spot for that instant. If the graph of the derivative crosses from positive x to negative x, then this indicates a local maximum. Likewise, if the graph of the derivative crosses from negative x to positive x then this indicates a local minimum.
What is the y-intercept of a linear equation?
The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
How do you find the zeros in an equation by looking on a graph?
They are all the points where the graph crosses (or touches) the x-axis.

What is the value of y at a point on a quadratic graph when it crosses the x axis?
zero
What happens when the y-intercept is changed?

The point or points at which a graph crosses the y axis what is that called?
They are called y-intercepts.
Is a horizonal line crosses the graph of a function of f at more than one point?
It can do.
What is the role of the y-intercept in a function?
is shows the point where a graph crosses the y-axis
