Write an equation of the line in slope intercept form

Find the y-intercept of the line. But the best part about the slope-intercept form is that you can read off the slope and the intercept right from the equation. We say that the equation is in slope—intercept form. Affiliate Common exercises will give you some pieces of information about a line, and you will have to come up with the equation of the line.

slope intercept form graph

There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books. The y-intercept is the point 0, 1. The red lines show us the rise is 1 and the run is 2.

how to find the equation of a line on a graph

For a review of how this equation is used for graphing, look at slope and graphing. Recognize the Relation Between the Graph and the Slope—Intercept Form of an Equation of a Line We have graphed linear equations by plotting points, using intercepts, recognizing horizontal and vertical lines, and using the point—slope method.

I think the most useful form of straight-line equations is the "slope-intercept" form: Affiliate This is called the slope-intercept form because "m" is the slope and "b" gives the y- intercept.

Use the graph to find the slope and y-intercept of the line. Add: If you missed this problem, review Figure. If you see an equation with only x and y — as opposed to, say x2 or sqrt y — then you're dealing with a straight-line equation.

The equation of this line is: Notice, the line has: When a linear equation is solved forthe coefficient of the term is the slope and the constant term is the y-coordinate of the y-intercept.
