How To Write Slope Intercept Form
Next find the coordinates of the y intercept this should be of the form 0 b.
How to write slope intercept form. This is the value of m in the equation. Y 3x 5 4. Example of the slope intercept form. Take the point 5 3 and substitute into the equation of the line. Y 3 5 x 4.
To write an equation in slope intercept form given a graph of that equation pick two points on the line and use them to find the slope. This is called slope intercept form because m is equal to the slope of the line and b is the value of y when x 0 which makes it the y intercept. Where c is the x value that all the points will share. Y 3x 5 4. The problem is that a vertical line has an undefined slope and unless the vertical line is the y axis it will not have a y intercept b.
Use the slope intercept formula to find the slope. The standard form of such an equation is ax by c 0 or ax by c. Put all these values together to construct the slope intercept form of a linear equation. B the y intercept. Write the following slope intercept form equation of a line in standard form.
Video tutorial on slope intercept form. Let s take a look at intercepts. When you rearrange this equation to get y by itself on the left side it takes the form y mx b. B y m x 1 2 1 1. Y 7x 2 1 4.
But we need to use inequality which satisfies the shaded region. Y 3x 4. You can also use x and y instead of x and y here. The y coordinate is the value of b in the equation. The slope of the line is 3 and the.
