The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: Show
Example 1
This equation is in slope intercept form. The y intercept is (0,-13) and the slope is 7. Example 2
Rewrite this equation in slope intercept form.
The equation is now in slope intercept form. The y intercept is (0,4) and the slope is Example 3
Rewrite this equation in slope intercept form.
The equation is now in slope intercept form. The y intercept is (0,-5) and the slope is Example 4 The equation is now in slope intercept
form. The y intercept is (0,-7.5) and the slope is [Index] The general formula for slope-intercept form is , where represents the slope of the line, and represents the -value of the line’s -intercept. The slope-intercept form of a linear equation makes it easier for us to identify how steep a line is and where it crosses the -axis. ✨ Drag the points on the graph to see how they affect the equation of the line! ✨ When we're given , we first need to find the slope. Then, we can use the slope and one of the given points to solve for the -value of the -intercept and write the equation in slope-intercept form. What is Standard Form?The general formula for the standard form of a linear equation is , where , , and are all integers. We can go from standard form to slope-intercept form by isolating and simplifying: What is Point-Slope Form?The general formula for the point-slope form of a linear equation is , where represents the slope of a line that contains the point (, ). We can go from point-slope form to slope-intercept form by isolating and simplifying: Check out our or explore our and sections to learn more about slope-intercept form and test your understanding.

Let's first quickly review slope intercept form. 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-InterceptWrite the equation for a line that has a slope of -2 and y-intercept of 5. NOTES: I substituted the value for the slope (-2) for m and the value for the y-intercept (5) for b. The variables x and y should always remain variables when writing a linear equation. In the example above, you were given the slope and y-intercept. Now let's look at a graph and write an equation based on the linear graph. Example 2: Writing An Equation Based on a GraphWrite an equation that represents the following graph.
