On graph paper, make a complete graph of the line .

  1. What is the slope angle of the line? That is, what is the acute angle the line makes with the ‑axis?

  2. Write the equation of a new line that has a slope angle of and passes through the point . Assume that the slope is positive.

    A angle means that and have a one to one ratio. What does that make the slope?

  3. Solve for the intersection of these two lines using any method. Write your solution as a point in the form .

    Use the Equal Values Method or substitution.
