## How do you find the x-intercept and y-intercept of a line?

To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis. When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. To find y-intercept: set x = 0 and solve for y.

## What are the 3 ways of finding the x and y-intercepts of a linear equation?

Finding x-intercepts and y-intercepts

- To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
- To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
- To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

**How do you find the x-intercept of a linear equation?**

Note: 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 of a function?**

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 .

### How do you find the y-intercept of a linear function?

The y intercept is the point where the line crosses the y axis. At this point x = 0. To find the x intercept set y = 0. To find the y intercept set x = 0.

### How do you find the x-intercept of a linear function?

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 does linear function look like?**

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x – 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x – 2.

**How do you find a linear equation?**

Solving Linear Equations

- Clear fractions or decimals.
- Simplify each side of the equation by removing parentheses and combining like terms.
- Isolate the variable term on one side of the equation.
- Solve the equation by dividing each side of the equation.
- Check your solution.

#### How do you find linear function?

A linear function is represented by the equation y = mx + b where:

- y = the y-coordinate.
- m = the slope of the line, or how steep it is.
- x = the x-coordinate.
- b = the y-intercept, or where the line crosses the y-axis on a graph.
