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?
Please show the graph work so that I may compare.
====================================================
The distance from the face of the building = x
The height of the beam = y
Therefore, solve for y when x = 30
y = (-2/3)*30 + 30 = 10
So the height is 10 ft.
