12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be. How to write the slope-intercept form given the slope and the y-intercept. Then slope m 13.
It was changed to y -1x 12 so it will look like y mx b slope intercept form.
Y m x b. Slope-intercept equation from slope point. The equation of a horizontal line is y b where b is the y-intercept. 7y -5x - 1.
