In mathematics, linear refers to an equation or function that is the equation of a straight line and takes the form y = mx + b, where "m" is equal to the slope, and "b" is equal to the y-intercept. Three features define ... More »

To write the equation of a line, find the slope and the y-intercept, and incorporate them into slope-intercept form. If you do not know the slope and the intercept, you can also use point-slope form, as long as you have ... More »

Find the slope of the line (m), and the place where the line crosses the y-axis, known as the y-intercept (b), to write the equation in slope-intercept form, y = mx + b. Use the equation to find the y value for any x on ... More »

The y-intercept is the point in a function where the value of the x-coordinate is zero. By definition, a function has only one y-intercept. The x-intercept is the point in a function where the value of the y-coordinate i... More »
