How Do You Calculate The X-Intercept Of A Line From Its Equation?
This free online math help will show you how to determine a line’s x-intercept. Finding the x-intercept of a line is one of the most common basic math algebra problems. Plug in zero for y. The idea behind this is that the x-intercept of a line is the point where y equals zero. Hence you plug in zero for y. Let’s consider the following math example: 2y + 4x = 24 , now plug in zero for y 0 + 4x = 24 4x = 24 Solve for x. The value of x that you find will be the x-intercept: 4x = 24 , divide by 4 on both sides to solve for x x = 6 So the x-intercept is x=6, and the line given line crosses the x-axis at (6,0) Practice makes perfect. We improve math skills through practice and math examples. Here are a few y = x + 6 , x-intercept is -6 9y + 4x = 2, x-intercept is ½ Ax + By = C where A, B, and C are non-zero constants, x-intercept is C/A Go to http://studentoffortune.com/#launch and enter your question or tutoring request in the text box provided.
