Question 474909: 6. Our equation y = 2.09x + 15.50 represents our charge for hats. An estimate from a competing company, Lotsa Hats, was -2.09x + y = 13.30.
A. Do you expect these lines to be parallel, perpendicular, or intersecting? Why?
B. Use the equations to determine if the lines are parallel. Are they? Why or why not?
You can put this solution on YOUR website! y = 2.09x + 15.50 ...........1
-2.09x + y = 13.30.
rewrite this equation
Equation (1) & (2) are having same slope of 2.09
Hence they will be parallel lines
