Write the equation of the line that has a slope angle of and a -intercept of . Sketch a graph of this line. Assume the slope of the line is positive.  .

Since the  then the

Substitute the slope () and the -intercept () in the form for a line.

Note: When a  -intercept is given as a point, the -intercept in an equation is the -coordinate only!
