How To Write Slope Intercept Form
The slope intercept form is probably the most frequently used way to express equation of a line.
How to write slope intercept form. Y the y coordinate. 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. Y mx b x and y are your variables. But we need to use inequality which satisfies the shaded region. Y 3x 5 4.
M y y x x 3 1 2 1 2 1 2. The standard form of such an equation is ax by c 0 or ax by c. This is the value of m in the equation. To be able to use slope intercept form all that you need to be able to do is 1 find the slope of a line and 2 find the y intercept of a line. Y 3 5 x 4.
In the slope intercept formula these variables are used. This video shows how to write equations in slope intercept form given an equation in standard form or any other form. Slope intercept form is y mx b. Use the slope intercept formula to find the slope. Video tutorial on slope intercept form.
Where c is the x value that all the points will share. Now have a look at the following example. The slope of the line is 3 and the. B y m x 1 2 1 1. Slope 3 5 y intercept 5.
Y mx b. 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. Next find the coordinates of the y intercept this should be of the form 0 b. When you rearrange this equation to get y by itself on the left side it takes the form y mx b. The y coordinate is the value of b in the equation.
