Designing a graph from this equation is easy especially when values are simpler. Knowledge of the y intercept can be used when graphing lines or when writing an equation in slope-intercept form.

The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation.

How to find slope y intercept and equation of line. To find the slope and y-intercept of a line you have to write the equation of the line in the form y mx b Here m stands for slope of the line and c stands for y-intercept. Finding an Equation of the Line Given the Slope and y-Intercept We can easily determine the slope and intercept of a line if the equation was written in slopeintercept form y mx b. This is a sensible equation that can also be named as the slope-intercept form.

Assuming youre talking about a linear straight-line equation you would use the standard slopey-intercept form y mx b. 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. Substitute the known slope for m and substitute the known points coordinates for x and y respectively in the slope-intercept equation.

Y mxb - 0mxb - -mxb - x intercept -bm. The slope m m m. Determine the slope and y-intercept from the following equation.

As we have seen before you can write the equation of any line in the form of y mx b. So the x-intercept is - y-interceptslope. So the equation of a line we can write as y is equal to mx plus b.

For example if the slope is 3 and the y-intercept is -5 the equation would be y mx b 3x -5 3x - 5. Alsosince the line is horizontal every point on that line has the exact same y value. Y y-intercept can easily be identified or read off from this form.

Y mx b. Y 5x - 2. So the general equation of the required line is.

Use the given slope for m the coefficient of x. Write the equation of the line that has a slope of 13 and contains the point negative 12 negative 143. Each linear equation describes a straight line which can be expressed using the slope intercept form equation.

Slope y 2 y 1 x 2 x 1 11 7 5 3 4 2 2. Because the line cuts y-axis at -2 clearly y-intercept is -2. 5x - y - 2 0.

Use the given y-intercept for b the constant in the equation. Y m x b. The equation of a line in point-slope form can be written as.

The equation can be in any form as long as its linear and and you can find the slope and y-intercept. So sub 0 in for y and you get. Substitute the slope for m in the slope intercept form of the equation.

For the equation y mx b m is the slope of the line that is multiplied by x and b is the y-intercept or we can say the point where the line will cross the vertical y-axis. Y m x b y 2 x b. Thats why the y-intercept is b.

Our slope they tell us is 13. Find the Equation of a Line Given That You Know Its Slope and Y-Intercept The equation of a line is typically written as ymxb where m is the slope and b is the y-intercept. This is in slope-intercept form where m is our slope and b right over here is our y-intercept.

If you know the slope m any y-intercept b of a line this page will show you how to find the equation of the line. This y-value is therefore also the y-intercept. We get the y-intercept by using the equation of a straight line which is.

Using the slope-intercept form of the lines equation y mx b you solve for b which is the y-intercept youre looking for. Now consider the x-intercept. Y 32x 3.

Substitute 5 for m and -2 for b. That will let you find b. The equation of a horizontal line is y b where b is the y-intercept.

The y y y -intercept b b b the y y y -coordinate of the point at which the graph of the line crosses the y y y -axis If you know any two of these things you can find the equation of the line. Calculate the slope from 2 points. At the x-intercept the y value for a point is always 0 At the x-axis y 0.

5x - y - 2 0. The slope m and the y-intercept b of. Enter the linear equation you want to find the slope and y-intercept for into the editor.

Y mx b. Slope-Intercept Form of the Equation of a Line The linear equation written in the form large y mx b y mx b. Equation of a straight line in slope-intercept form is.

Find the equation of a line through the points 3 7 and 5 11 Step 1. Now we know that slope m 5 and y-intercept b -2. Now we will do the reversewe will start with the slope and y -intercept and use them to find the equation of the line.

Formula to calculate y-intercept. This is the so-called slope intercept form because it gives you two important pieces of information. And they have actually given us our slope.
