Question

At a local market, cost of apples is directly proportional to the weight of the apples. Carlos bought 10 pounds of apples for $15. If you graph the weight of apples on the x-axis and the cost of apples on the y-axis, what is the slope of the line that represents this relationship?

Assume that a consumer has a given budget or income of $12, and that she can buy only two goods, apples or bananas. The price of an apple is $1.50 and the price of a banana is $0.75. Refer to the information given above. What is the slope of the budget line, if the quantity of apples were measured on the horizontal axis and bananas on the vertical axis?

00:01 This problem says that the local market costs of apples is directly proportional to the weight of the apples.
00:06 Carlos bought 10 pounds of apples for $15.
00:08 If you graph the weight of apples on the x -axis and the cost of apples on the y -axis, what is the slope of the line that represents this relationship? so we are assigned which variable means what, and we're told that the x -axis represents the weight.
00:22 So our x values will come from the pounds of apples.
00:25 And our y values map out the cost of the apples, so the y values here would be $15...
