What is the difference of x intercept and y intercept?
The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
Is X is a rational number and Y is the opposite of X why do X and Y have the same absolute value?
X and Y have the same absolute value because the opposite of a number doesn't change its distance from zero. The absolute value of a number represents its distance from zero on the number line, and since X and Y are opposites, they have the same distance from zero.
What is the y-intercept of y equals 2x plus 10?
The y-intercept means... When does the line cross through the y-axis?This happens when the x-value is zero... so simply just plug in zero for "x"y = 2 * (0) + 10y = 10y-intercept is equal to 10For the x-intercept just make the y-value equal to zero.
Why do we substitute zero for the value of y when finding the solutions of quadratic equations?
Because the solutions are found on the x axis when y is zero.
What are the coordinates of the y intercept?
They are at (0, y) on the Cartesian plane where y is the vertical y axis. For any function you would have to solve the function for the value of y when x is zero - and then the coordinates would be (0,y) For the x (horizontal) axis, which is equivalent to the function y = 0, they would be (0,0), i.e. when x is zero, y is zero.

What happens to the graph when x is nearly zero?
When x is nearly zero,y increases in value.
Why is the zero of a function the same as an x-intercept of a function?
when you have a function lets say y = mx + b then you set it equal to zero and solve you are finding the x values that give you a y value of zero and a y value of zero lies on the x-axis. therefore when you find a zero of a function it's really the x value of where the function touches or crosses the x axis. hope this helps

What is the value of y for any point on the x axis?
It is zero

Is f(x) a function?
The zero of a f (function) is an x-value that corresponds to where the y-value is zero on the functions graph or the x-intercepts. Functions can have multiple zeroes or no real zeroes at all, depending on the equation.
Why do we substitute zero for the value of y when finding the solutions of quadratic equations?
Because the solutions are found on the x axis when y is zero.
How do you find the y-intercept of a function?
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.

What is the value of y at a point on a quadratic graph when it crosses the x axis?
zero
What is the point at which a graph intersects the y-axis?
A graph intersects the y-axis at the y-intercept; its x value is zero.
