Y mx b or sometimes y mx c m slope the amount of rise over run of the line b y-axis intercept where the line crosses over the y-axis To calculate the slope intercept form equation from two coordinates. The first step in finding the equation of a line perpendicular to another is understanding the relationship of their slopes. Therefore when youre writing the slope-intercept equation write the slope of the line in place of m.
12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be.
Similarly the form ymxa means slope m and y-intercept a. Therefore when youre writing the slope-intercept equation write the slope of the line in place of m. Image will be Uploaded Soon 1. The form ym x-a is essentially different from the other two forms and means slope m and x-intercept instead of y-intercept a.
