how to use slope intercept formula. You can use slope intercept form to solve for x y m and b. Using the slope-intercept form of the lines equation y mx b you solve for b which is the y-intercept youre looking for.
When the line is graphed m is the slope of the line and b is where the line crosses the y-axis or the y-intercept. When a linear equation is written in slope intercept form the slope of the line can easily be identified. M is the Slope of a line.
Y equals 2 x plus 3.
This lesson shows how to use the slope formula and two points from a line to determine the slope of the lineNeed More Algebra Help. Using Slope Intercept Form for Word Problems. So point x1 y1 is actually at 0 b. The slope-intercept form of an equation is y mx b which defines a line.
