Find the equation of the line that has a slope angle and a -intercept at . Assume the line has a positive slope.  

Sketch a graph and a slope triangle for the line.

Use the tangent ratio to find the slope:

Once you know the slope and the -intercept, you can write the equation of the line. You use slope-intercept form .
