Solution That was a pretty easy example. Write an equation in slope intercept form given the slope and y-intercept. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. Writing Equations in Standard Form We know that equations can be written in slope intercept form or standard form.

However, you must be able to rewrite equations in both forms. In the example above, you were given the slope and y-intercept. The following are examples of a rate: Solution Slope intercept form is the more popular of the two forms for writing equations.

Example 2 demonstrates how to write an equation based on a graph. We need to find the least common multiple LCM for the two fractions and then multiply all terms by that number!

Real World Problems When you have a real world problem, there are two things that you want to look for! How do we write an equation for a real world problem in slope intercept form? Calculate the slope from the y-intercept to the second point.

You have a positive slope. Locate another point that lies on the line. We now know that standard form equations should not contain fractions.

Yes, it is rising; therefore, your slope should be positive! When we move terms around, we do so exactly as we do when we solve equations! Remember standard form is written: Our first step is to eliminate the fractions, but this becomes a little more difficult when the fractions have different denominators!

For standard form equations, just remember that the A, B, and C must be integers and A should not be negative. Equations that are written in standard form: Whatever you do to one side of the equation, you must do to the other side!To summarize how to write a linear equation using the slope-interception form you.

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept.

This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b. Slope intercept form is the more popular of the two forms for writing equations. However, you must be able to rewrite equations in both forms.

For standard form equations, just remember that the A, B, and C must be integers and A should not be negative.

It is a common to ask to have to convert equation of line from slope intercept to standard form, as demonstrated by the pictures below. Example of Converting from Slope Intercept to Standard Form. Linear equations can take several forms, such as the point-slope formula, the slope-intercept formula, and the standard form of a linear equation.

These forms allow mathematicians to describe the exact same line in different ways. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. All you need to know is the slope (rate) and the y-intercept.

Continue reading for a couple of examples! Example 1: Writing an Equation Given the Slope and Y-Intercept.

Write the equation for a line that has a slope of.
