Question 170838
Leslie dives off a block at the edge of the pool. She enters the water 8 ft from the side of the pool. Leslie is 1 ft under water when she is 11 ft from the side of the pool. Write an equation that gives Leslie's depth, y, in terms of her distance from the side.
-----------------
You have two points relating (distance from side, depth)
(8,0) and (11,-1) 
slope = (-1-0)/(11-8) = -1/3
intercept: 0 = -(1/3)8 + b
b = 8/31
====================
Equation:
depth = (-1/3)distance  + 8/3
y = (-1/3)distance + 8/3
============================
