Before you move on to converting from point-slope form to slope-intercept form heres a quick recap of what point-slope form looks like. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. You can use slope intercept form to solve for x y m and b.
Once you know the slope m youre halfway there.
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. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. One way is to use the slope-intercept form. It was changed to y -1x 12 so it will look like y mx b slope intercept form.
