Intercept Equation Math

Also since the line is horizontal every point on that line has the exact same y value.

Intercept equation math. Let s set x equal to 0 so if we set x is equal to 0 we have negative 5 times 0 plus 4y is equal to 20. For k 12 kids teachers and parents. Well anything times 0 is 0 so we can just put that out of the way. So this just simplifies to 4y is equal to 20.

To find the intercepts. This y value is therefore also the y intercept. Where the graph of an equation crosses the y axis. So sub 0 in for y and you get.

Write down the equation of the line. What is the value of y when x is equal to zero. Y mx b 0 mx b mx b x intercept b m. The equation of a horizontal line is y b where b is the y intercept.

2 x plus 3 y equals 5. Y 10 100x y 10 100x. The answer is the. The x intercept of the equation 2x 7y 14 would be what answered by a verified math tutor or teacher we use cookies to give you the best possible experience on our website.

Y 10 100 x. The y axis is a vertical line along x 0. Using an equation 1. This means any point on the y axis has an x coordinate.

And then m is our slope. When you want the. At the x intercept the y value for a point is always 0 at the x axis y 0. The slope and y intercept calculator takes a linear equation and allows you to calculate the slope and y intercept for the equation.

The figure below shows an example of an x intercept green dot and a y intercept red dot. Y equals 10 minus 100 x. If you already have the equation of the line you can find the y intercept with. Where the graph of an equation crosses the x axis.

The equation can be in any form as long as its linear and and you can find the slope and y intercept. Math explained in easy language plus puzzles games quizzes worksheets and a forum. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. And remember this was setting x is equal to 0 we re doing the y intercept now.

The x intercept is the point at which a line crosses the x axis and the y intercept is the point at which a line crosses the y axis. And you d say all right when x is equal to zero she s at an elevation of 1 200. Substitute 0 for x. Now consider the x intercept.

Finding intercepts from an equation. 2 x 3 y 5. 2x 3y 5 2x 3y 5. The term intercept refers to the x and y intercepts of of a given equation.

You could say the slope intercept form for a linear equation is y is equal to mx plus b where b is your y intercept. But this equation has x in the last term on the other hand these linear equations are not in slope intercept form. Y equals minus 3 x plus 2 point 7.
