Match each of the following equations according to their slope and y-intercept.
y = 1.5x - 7
m = -1.5, b = -4
y = -1.5x - 4
m
= 3, b=0
y = -3x + 4
m= -3, b = 4
y = 3x
m
= 1.5, b = -7
y = 7
m = 0,b= 7
Intro

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
