how to find slope intercept form formula. Identify the coordinates x₁y₁ and x₂y₂. You may already be familiar with the ymxb form called the slope-intercept form of the equation of a line.
Finding the Y-Intercept from the Slope and Point 1. Slope Intercept Form Formula For the equation y mx b m is the slope of the line that is multiplied by x and b is the y-intercept or we can say the point where the line will cross the vertical y-axis. So point x 1 y 1 is actually at 0 b and the equation becomes.

This useful form of the line equation is sensibly named the slope-intercept form. I hope this helps. Simplify the fraction to get the slope of -25. This gives you the equation y 4x - 2 which is now in slope-intercept form.
