How Do You Find the Slope of a Line If You Have a Parallel Line?

Find the slope of a line that is parallel to the line y = 2x – 2.

Summary

  1. 'x' and 'y' are variables
  2. L1 is our line, y=2x-2
  3. L2 is a line that's parallel to L1
  4. Parallel lines never cross one another
  5. y=mx+b is the general slope-intercept form of a line
  6. 'b' is the y-intercept
  7. Parallel lines do not have the same y-intercept
  8. The coefficient in front of 'x' in slope-intercept form, 'm', is always the slope of the line

Notes

    1. Parallel lines never cross one another
    1. We need to pick out the slope of L1 by looking at the equation y=2x-2
    1. 'b' is the y-intercept
    2. Parallel lines do not have the same y-intercept
    3. The coefficient in front of 'x' in slope-intercept form, 'm', is always the slope of the line
    1. The coefficient in front of 'x' in slope-intercept form, 'm', is always the slope of the line
    2. In this case, m=2
    1. Any two parallel lines will have the same slope
    2. Since the two lines are parallel, L2 must have the same slope as L1, y=2x-2
