If for example: y = 2x+4
Then: y-2x = 4
And when the value of x is 0 then the y intercept is 4
And when the value of y is 0 then the x intercept is -2

How are solution and x-intercept and zero of a function and and root related?
solutions are the well solution to the problem. X-intercepts are wherever a graph cross the x axis, which are hte solutions when you have to find out what x is, zeros are pretty much the same thing although i think that include y-intercepts as well..... not sure. and roots are the same thing as x-intercepts. so they are all more or less the same thing
What is x-intercept and y-intercept?
The graphical concept of x- and y-intercepts is pretty simple. The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. The problems start when we try to deal with intercepts algebraically.To clarify the algebraic part, think again about the axes. When you were first introduced to the Cartesian plane, you were shown the regular number line from elementary school (the x-axis), and then shown how you could draw a perpendicular number line (the y-axis) through the zero point on the first number line. Take a closer look, and you'll see that the y-axis is also the line "x = 0". In the same way, the x-axis is also the line "y = 0".Then, algebraically,an x-intercept is a point on the graph where y is zero, anda y-intercept is a point on the graph where x is zero.More specifically,an x-intercept is a point in the equation where the y-value is zero, anda y-intercept is a point in the equation where the x-value is zero.
When the graph of a quadratic function crosses the x-axis twice the x-coordinate of the vertex lies between the two x-intercepts?
The x co-ordinate of a quadratic lies exactly halfway between the two x-intercepts, assuming they exist. Alternatively, the x co-ordinate can be found using the formula -B/(2A), when the function is in the form, y = Axx + Bx + C.
Why can two different linear functions have the same y-intercept?
Because a linear function just has to be a strait line which is not vertical at any point (stait), the two lines can be positioned anywhere on a graph with the same y intercepts. For instance, you could have a big "x" on the graph, where the lines cross on the y line, and have their y intercepts be the same.
How do you find x and y intercepts to this 4x -20?

Why do you need x intercepts for quadratic equations?
so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis
How do you find x- and y- intercepts given a graph?
by shoving it up your booty
How do you find the maximum height of a parabolic path?
If "a" is negative then the graph is a cap. Find the x intercepts. Average the two x intercepts and substitute that into the equation it will give you the y.
How do you determine the intercepts from an equation or graph?
From the equation, the y intercept is simply determined by setting x = 0. The x intercept(s) are generally much harder to find: you will need to find the solutions of y = 0 [or f(x) = 0]. From the graph the intercepts are the coordinates of the points at which the graph crosses the axes.
How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
How do you find x and y intercepts?
if you are looking at a graph the y intercept is when the graph crosses the y axis and the x intercept is when the graph crosses the x axis. if you have a formula... plug zero in for x to find the y intercept, and plug zero in for y to find the x intercept
What are x and y intercepts?
The x and y intercepts are where a line on a graph intersects (crosses over) the x or y axis.
Can you graph x4 10x2 33x2 38x 8 numbers in parentheses are exponents Find All X-Intercepts Y Intercept Turning points?
Can you Graph: x4 +10x2 + 33x2 + 38x +8 Find: All X-Intercepts, Y-Intercept, Turning points
What is the point where a graph intercepts the x-axis?
The point where a graph intercepts the x axis may have several names. It could be called an x-intercept, a root, or a solution.It is at: (x, 0).
How d yu find x and y intercept on a graph?
In the equation y = f(x), Put x = 0 and solve for y. Those are the y intercepts. Put y = 0 and solve for x. Those are the x intercepts.
If you are looking a graph of an quadratic equation how do you know where the solutions are?
They will be on the horizontal x axis of the graph (look for the x-intercepts).
How do you graph y x 2?
It is a line. There are many ways to graph it using intercepts etc. But, you can pick some x points, plug them in your equation, and find the corresponding y point, The graph those (x,y) values
