# How do you find the x and y intercepts on a graph?

## How do you find the x and y intercepts on a graph?

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.

**What is the x-intercept in a formula?**

To find the x-intercept of an equation, set the value equal to zero and solve for . Subtract from both sides.

### How do you find the x-intercept when given two points?

Put the value of the slope in the expression of the line i.e. y = mx + c. Now find the value of c using the values of any of the given points in the equation y = mx + c. To find the x-intercept, put y = 0 in y = mx + c. To find the y-intercept, put x = 0 in y = mx + c.

**What is x-intercept of a line?**

The x intercept is the point where the line crosses the x axis. The y intercept is the point where the line crosses the y axis.

## What is x-intercept example?

The x -intercepts of a function are the point(s) where the graph of the function crosses the x -axis. The x -intercept is often referred to with just the x -value. For example, we say that the x -intercept of the line shown in the graph below is 7 .

**What is an example of a y-intercept?**

The y -intercept of a graph is the point where the graph crosses the y -axis. When the equation of a line is written in slope-intercept form ( y=mx+b ), the y -intercept b can be read immediately from the equation. Example 1: The graph of y=34x−2 has its y -intercept at −2 .

### How do you find y-intercept on a table?

When finding Y Intercept from a graph, you find the point where the graph of the equation crosses the y-axis. When finding Y Intercept from a table, you find the y-value when the x-value is equal to zero. If you do not know what the x-value is equal to when its zero, you must use the slope to go backward to find it.

**What is the x-intercept variable?**

In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y and an x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system.

## What is x-intercept format?

A linear equation has the form y = mx + b, where M and B are constants. The x-intercept is the point where the line crosses the x-axis. By definition, the y-value of a linear equation when it crosses the x-axis will always be 0, since the x-axis is stationed at y = 0 on a graph.

**How do you solve for the x intercept?**

Using the Equation of the Line Determine that the equation of the line is in standard form. The standard form of a linear equation is Ax+By=C{\\displaystyle Ax+By=C}. Plug in 0 for y{\\displaystyle y}. The x-intercept is the point on the line where the line crosses the x-axis. Solve for x{\\displaystyle x}.

### What is the equation for x – intercept?

X-Intercept. A linear equation has the form y = mx + b, where M and B are constants. The x-intercept is the point where the line crosses the x-axis. By definition, the y-value of a linear equation when it crosses the x-axis will always be 0, since the x-axis is stationed at y = 0 on a graph. Consequently, to find a y-intercept,…

**How do you Find X in an equation?**

You can find “x” or solve the equation for “x” by isolating the “x” on one side of the algebraic equation. To solve for “x”, you need to understand the basic rules of algebraic operations. Isolate “x” on one side of the algebraic equation by subtracting the sum that appears on the same side of the equation as the “x.”.

## How do find the y intercept?

Find the Y intercept. Press the “Trace” button. Press the “0” button. This will move the cursor to the Y intercept where X = 0. Look at the bottom of your screen; the Y-intercept will be displayed there.
