Question

the scatter plot shows the price in dollars, and the corresponding area, in square feet, of the houses for sale in a certain township.

Answer 1

The relationship between price and area is " An estimated increase in area of 100 ft² corresponds to an increase of $10000 in price. Hence, option C is correct.

Using the pair of points to calculate the slope ;

• (2500, 400000) ; (1500, 300000)

The rise = (300000 - 400000) = -100000

The run = (1500 - 2500) = - 1000

Comparing the change ; -100000 / -1000 = 10000 / 100

The slope is positive, hence, the price increases as the area of the house increases .

Hence, option C is correct .
