How might a drop in price for washing machines affect the demand for dryers? a) the demand for dryers would have no relation to the changing prices of washing machines. b) the demand for dryers would most likely increase as the price for washing machines dropped. c) the demand for dryers would most likely decrease as the price for washing machines dropped. d) the demand for dryers would only be affected by an increase in the price of washing machines. b

This problem asks about supply and demand. There are tow variables - dependent and independent. The price for a washing machine is independent to the price of the Dryer in this situation, as you don't need a dryer if you have a wash. If you have a washer, the likelihood of you needing a dryer is larger. If you need to buy a dryer, and the price has dropped, this will create more buyers, as more will be able to afford them. This gives the answer B.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
