Standard to slope-intercept formĬonverting from standard form to slope-intercept form involves manipulating an equation in standard form so as to isolate y on one side of the equation such that the coefficient on the y is 1.Write the equation of the red line in slope-intercept form. It is relatively common to need to convert the equation of a line in standard or point-slope form to slope-intercept form.

Using one point and slope What is the slope-intercept form of a straight line if Slope 4. Solution: Step 1: Identify the given information. It can also be used to write the equation of vertical lines, something that cannot be done using slope-intercept or point-slope form. Using slope and y-intercept: If a straight line has a slope of -1 and its y-intercept is 3. Standard form is useful when we are trying to solve systems of linear equations. The standard form of the equation of a line is Point-slope form is useful when a point on the line and the slope of the line are known, since it enables us to write an equation for the line. In the equation, y 1 and x 1 indicate a point on the line that is not the y-intercept, while m is the slope. Slope-intercept form is useful because the slope and y-intercept of the line can easily be read off the equation, which also makes it relatively easy to graph the line, since we can just start from the y-intercept and find another point on the line by counting the rise over run (slope) in the coordinate plane. Other commonly used forms include point-slope form and standard form. Depending on the context that a linear equation is being used in, certain forms can be more beneficial to use. Slope-intercept form is just one of a number of different forms of linear equations, albeit it is the most commonly used form. Thus, the y-intercept occurs at the point (0, 3). For example, given the line 3x + 2y = 6, the y-intercept can be found by plugging 0 in for x, then solving for y. It follows that, given an equation, setting x equal to 0 and solving for y will yield the y-intercept of the line. If a graph is given, the point at which the line intersects the y-axis is the y-intercept. Step 1: Enter the linear equation you want to find the slope and y-intercept for into the editor. Where m is the slope and b is the y-intercept.

The y-intercept can be found in a number of ways. In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function. Given at least two points on a line, the slope of the line can be found using the slope formula:įor example, given the that (1, 5) and (-2, 7) are points on the same line, the slope of the line can be found as follows: How to find the slope and the y-intercept Once the slope and y-intercept are known, writing the equation of the line just involves plugging the slope and y-intercept into m and b respectively. We found the y-intercept by plugging the given values into the equation y = mx + b, then solving for b. y = mx + bīecause we are given slope and a point on a line, we just need to find the y-intercept in order to write the equation of the line in slope-intercept form. Given m = 3 and the point (3, 5), find b, and write the equation of the line in slope-intercept form.
