5-57.

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

What is the slope angle of the line? That is, what is the acute angle the line makes with the

‑axis?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 andhave a one to one ratio. What does that make the slope?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.
