Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

x intercept calculator is used to find the x intercept in the equation of the straight line. We can get the x intercept of a straight line from the form (x/a) + (y / b) = 1. Here, a is the x – intercept and b is the y – intercept.

Example 1: Find the x – intercept of the equation of the line 7x + 3y = 21.

We can convert the given equation into (x/a) + (y/b) = 1

Here a is the x intercept

To convert into this form, first we can divide this equation by 21

Then we have (7x/21) + (3y/21) = 1

We can write above equation as (x/ 3) + (y/7) = 1

Here, x intercept = a = 3.

Example 2: Find the x – intercept of the equation of the line 5x + 4y = 20.

We can convert the given equation into (x/a) + (y/b) = 1

Here a is the x intercept

To convert into this form, first we can divide this equation by 20

Then we have (5x/20) + (4y/20) = 1

We can write above equation as (x/ 4) + (y/5) = 1

Here, x intercept = a = 4.
