From the y-intercept point use the slope to find a second point. Y mxb - 0mxb - -mxb - x intercept -bm. You can use the calculator below to find the equation of a line from any two points.
In the equation of a straight line when the equation is written as y mx b the slope is the number m that is multiplied on the x and b is the y - intercept that is the point where the line crosses the vertical y -axis.
You can use slope intercept form to solve for x y m and b. From the y-intercept point use the slope to find a second point. In the equation of a straight line when the equation is written as y mx b the slope is the number m that is multiplied on the x and b is the y - intercept that is the point where the line crosses the vertical y -axis. Divide each term by 2 2 and simplify.
