A market research company finds that at a price of p=$20,they would sell x=42 tiles each month. If they lower the prcie to p=$10,then more people would purchase the tile,and they can expect to sell x=52 tiles in a months time. Find the equation of the line for the demand equation. The equation needs to be in the form p=mx+b.
