 Question 609975: Suppose a market research company finds that at a price of p = \$30, they would sell x = 45 tiles each month. If they lower the price to p = \$20, then more people would purchase the tile, and they can expect to sell x = 60 tiles in a months time. Find the equation of the line for the demand equation. Write your answer in the form p = mx + b. Hint #1: Write an equation using two points in the form (x, p). Hint #2: The slope formula is needed. Click here to see answer by stanbon(57361)

 Question 610832: Hello So I have a test on polynomial stuff, factoring, completing the square, factoring trinomials, how to change from one form of an equation (general, vertex, factored form) is there any easy way to remember all this stuff because it seems for each equation you're doing somthing different and I'm so lost... Is there an easy way to remember it all? Click here to see answer by Alan3354(30993)
