On this line y =0.15x+ 0.79 is the representation of the average cost of gas each year. 0.11x -y= -0.85 estimates the price of gas in January of each year. Do these lines expect to be insecting, parallel, or perpendicular? Use the equation of the lines to determine if they are parallel and what was found? Please advise. Thank you.
