# Write an equation in slope intercept form from a graph

Since the run is positive 3, I counted to the right 3. And b is the y-intercept. You must have at least two points to draw a line. The rate is your slope in the problem. So that right there is our m.

In this example, we are only focusing on how to count the slope and plot the next point. Repeat the process to plot a third point. So our change in x is equal to 4.

For every 5 we move to the right, we move down 1. Let's figure out its slope first. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. As shown above, whenever you have a vertical line your slope is undefined. So our delta x could be 1. The polynomial 0, which may be considered to have no terms at all, is called the zero polynomial.

I think you get the idea. Let's do this first line. Where is this x term? For polynomials in one indeterminate, the evaluation is usually more efficient lower number of arithmetic operations to perform using Horner's method: You could view this as plus 0.

If you said vertical, you are correct. Our delta y-- and I'm just doing it because I want to hit an even number here-- our delta y is equal to-- we go down by it's equal to negative 2. Negative 1, negative 2, this is the point 0, negative 2. Now let's go the other way.Given the slope and y intercept, write the equation of a line 3.

Use the slope and y intercept to graph a line The Slope-Intercept Form for a Line equation is solved for y. The coefﬁcient of x will give you the slope of the line, and the Graphing by Using the Slope-Intercept Form.

Sep 09,  · This video provides an example of how to determine the equation of a line in slope intercept form given the graph of a line. Graph a Linear Equation in Point-Slope Form Writing Linear. The slope-intercept form of a linear equation Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C.

Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b. The slope-intercept form of an equation of a line that has a slope m and a y-intercept (0, b) is given by the formula y = mx + b in slope-intercept form, the m is only the coefficient of x, the variable part is not included in the slope.
