Search for key terms or text.

Cool Down

On the same coordinate grid:

  • Partner A draws a vertical line, and Partner B draws a horizontal line.
  • Each partner labels their line with its equation in slope-intercept form.

Pass your paper to your partner. Check your partner’s graph and equation.

1.

Explain if your partner graphed the equation correctly and labeled the line with the correct equation.

For question 2, complete the following tasks:

  • Draw a point on your partner’s paper that is not on the line.
  • Label the point P.
  • Draw a line parallel to the original line through point PP.
2.

What is the equation of the line that passes through point PP and is parallel to your partner’s original line?

3.

Draw a line perpendicular to the original line that goes through point PP. What is the equation of the line that passes through point PP and is perpendicular to your partner’s original line?
