This is the most common and user-friendly form when graphing linear equations, especially if you know the slope and y-intercept. Home; Reviews; Courses. My name is Lauren Casias. Different shapes can be used to express the equation of a straight line A Special Case of the Point-Slope Form. b is the y-intercept (the point where the line crosses the y-axis). Finally, draw a straight line through the two points. Start by plotting the y-intercept (0, -1) on the y-axis. com | Here's how to take any linear equation (in standard form, slope-intercept form, or whatever), and rearrange it so it looks like y This is the same line that I found on the previous page, so I already know what the answer is (namely, y = 4x − 2). the midpoint calculator or by simply taking the average of each x-coordinates and the average of the y-coordinates to form a new coordinate. But what happens when you have another point instead of the y-intercept?. Every point on the line has x coordinate 1. ADD x1 to x2 (also means add or . Equation of a straight line can also be evaluated with one point and slope using our point slope form calculator. Using an equation in the point-slope form allows you to identify the slope and a point. It’s clear that we should substitute \(−3/2\) form.
