C.
John and Susan are selling lemonade at the same price.

D.
The less expensive stand cannot be determined based on the information given.

Answer 1

`\displaystyle Susan's\:lemonade\:stand\:is\:less\:expensive.`

Step-by-step explanation:

Starting from the y-intercept of
`\displaystyle [0, 8],`you do
`\displaystyle (rise)/(run)`by moving four blocks north over 8 blocks east [west and south are negatives] to get
`\displaystyle (1)/(2), or\:0,5.`The rate of change [slope] of John's earnings is
`\displaystyle 1(3)/(4), or\:1,25,`while Susan's is 0,5, therefore you have your answer.
