In the United States, most building codes limit the steepness of the slope of a roof to 4/3, as shown at the right. A builder wants to put a support brace from Point C perpendicular to AP. Find the length of the brace.

Aline passes through the points (5,4) and (2.1). part a.) what is the slope of the line that passes through these points? show work. part b.) what is the equation of the line that passes through these points. show work. part c.) where does the line intercept on the x& y axis? show work
