A candle burned at a steady rate. After \( 32 \) minutes, the candle was \( 11.2 \) inches tall. Eighteen minutes later, it was \( 10.75 \) inches tall. Use an equation in point-slope form to determine the height of the candle after \( 2 \) hours. 

Answer

y = -0.025x +11.2 +  0.025*32 = -0.025x + 12

-0.025*120 + 12 = 9 inches

so the height of the candle after 2 hours is 9 inches.
