How do I determine the height of the laser beam 30 ft away from the face of the building if the equation is y=-(2/3)x+30?\r

\n" ); document.write( "====================================================
\n" ); document.write( "The distance from the face of the building = x
\n" ); document.write( "The height of the beam = y
\n" ); document.write( "Therefore, solve for y when x = 30
\n" ); document.write( "y = (-2/3)*30 + 30 = 10
\n" ); document.write( "So the height is 10 ft.
