You can find the y-intercept for a linear equation in any form by setting x to zero and solving for y. Similarly, you can find the x-intercept by setting y to zero and solving for x.
In the above general equation, the x-intercept is -b/m.

Working from a graph:
The x-intercepts are the points where the graph cuts the x-axis. The y-coordinates of these points are 0.
The y-intercepts are the points where the graph cuts the y-axis. The x-coordinates of these points are 0. A function cannot do this since then it would be a one-to-many mapping which is NOT a function. However, some equations (eg a circle) may give rise to more than one y-intercepts.
Working from an equation:
Let y = 0 and find the values of x that satisfy the equation. These are the x-intercepts.
Let x = 0 and find the values of y that satisfy the equation. These are the y-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
How do you find x-intercept?
To find the x-intercept you need to set y=0 in your equation. To find the y-intercept you need to set x=0 in your equation.
True or false given a linear equation in two variables x and y the x intercept is found by setting x equal to zero and solving for y?
False. To find the x-intercept, let y = 0 and solve for x. To find the y-intercept, let x = 0 and solve for y.
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.
How do you find the x intercept on a linear equation?
At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.
How do you find x intercept and the meaning and y intercept?
solve the x and you find the y
What is y intercept and x intercept of y x plus 8?
To find the y intercept put zero in for x and solve. To find the x intercept put zero in for y and solve. (0,8) and (-8,0)
How do you find x intercept?
to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
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)
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 is the x and y intercept of 2x plus 3y equals -12?
To find the y-intercept, plug 0 in for x: 3y = -12 y = -4To find the x-intercept, plug 0 in for y: 2x = -12 x = -6The y-intercept is y = -4, and the x-intercept is x = -6.
How do you find the x-intercept from a table?
You look for the value of 0 in the y column, and find out what x has to be for y=0. This value of x is you x-axis intercept. (Reverse "x" and "y" in the above description to find the y-intercept, if there is one).
How do you find x-intercept?
To find the x-intercept you need to set y=0 in your equation. To find the y-intercept you need to set x=0 in your equation.
How do you find the x and y intercepts of an equation?
Substitute zero for x to find the y-intercept, and substitute zero for y to find the x-intercept.
How do you find the y-intercept and x-intercept of y equals -1?
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
How do you find the intercepts of 4y-12 equals 4x?
To find the y-intercept you substitute in 0 for x and solve. To find the x- intercept you substitute in 0 for y and solve. If you do it correctly you should find the x-intercept to be -3 and the y-intercept to be 3.
Find the y-intercept of y equals 2x?
Normally, the y-intercept would be after the x term, but because there is no x term the y-intercept is 0.
