Question 318077: a) A water line is given by the equation
y=0.6x-3.2
.
Suppose you want to put a pink flamingo lawn ornament in your backyard, but you want to avoid placing it directly over the water line, in case you need to excavate the line for repairs in the future. Could you place it at the point ? Support your answer with complete algebraic detailed calculations.

b) What is the slope and y-intercept of the line in part a? How do you know?
