Since the slope of a horizontal line is 0 the general formula for the standard form equation y. Using a Graph to Find the Slope. Draw dots on the graph to represent these.
M is the Slope of a line.
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. By examining the equation of a line you quickly can discern its slope and y-intercept where the line crosses the y-axis. Y y-intercept we need to make sure that the equation of the line is in the Slope-Intercept Form From this format we can easily. The equation of a horizontal line is y b where b is the y-intercept.
