## 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

1. Clear fractions or decimals.
2. Simplify each side of the equation by removing parentheses and combining like terms.
3. Isolate the variable term on one side of the equation.
4. Solve the equation by dividing each side of the equation.
