Jen is building a doll house for her daughter. She decided that she wanted the slope of the roof to be 3/4. In the blueprint, the roof starts at (-6,10) and the center of the house is at (0,0). Knowing that the peak of the roof will be at (0,y), what y-coordinate will make the slope of the roof 3/4?

1 answer

∆y/∆x = 3/4
∆x = 6, so ∆y = 9/2
(0,y) = (0,14.5)
