It is the same equation in a different form. Quick tutorial on finding the slope from an equation. Check it out on the video Worked example.
Displaystyle y mx b Note- The slope of two parallel lines is always equal.
The slope-intercept form of a line. 12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be. Calculate the slope from 2 points. Y m x b.
