a, b and c can be entered as integers, fractions or numbers with a decimal point as shown below.įor lines of the form ax = c (b = 0), the slope is undefined. To calculate the inverse of a function, swap the x and y variables then solve for y in terms of x. Use Slope Intercept Form of a Line Calculatorġ - Enter the coefficients a, b and c and press 'Slope Intercept Form'. The general formula for slope-intercept form is y mx + b, where m represents the slope of the line, and b represents the y. For example, when you have the equation in slope intercept form, using the line formula. The importance of the slope intercept form of a line lies in the fact that the slope m and the y intercept B of the line are easily identified and here are the steps to follow:ġ) Solve the general equation a x + b y = c for yįor b not equal to zero, we divide all terms by the coefficient b.Ģ) Compare the above equation to the slope intercept form y = m x + B and identify m and B asįind slope and the y intercept of the line given by the equation 2 y + 3 x = 6Ĭompare the above equation to the slope intercept for y = m x + B to find The ideal way, though, it is calculate the y-intercept algebraically. Into the slope intercept form y = m x + B.

The equation of a line in the slope-intercept form is ymx+b Example: Consider a line with a slope of 2 and a y.

The slopeintercept form of an equation of a line with slope m and y-intercept, ((0,b)) is (ymx+b) This page titled 3.3: Slope Intercept Form is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by Stanislav A. The slope determines the lines steepness, while the y-intercept indicates where the line crosses the y-axis. Slope Intercept Form of an Equation of a Line. Use slope intercept form calculator to find the equation of a straight line using slope intercept formula (function) ymx+b, two points, or one point and slope. This online calculator rewrites an equation of a line of the general form This widely-used form represents a lines equation using its slope m and y-intercept b. One, of the mathematics formula variety, is the Slope Intercept Form Calculator. Every point on the line has x coordinate 1.5, that is why its equation is x 1. In fact, this is a special case, and we use a different equation, not 'y.', but instead we use 'x. Equations of a Straight Line: a line through two points, through a point with a given slope, a line with two given intercepts, etc. Slope Intercept Form of a Line - Calculator What is the equation for a vertical line The slope is undefined.
