Question

Mickey used to work at Best Buy and was also offered that other job at The Digital Source. In the end, she declined both of those jobs in order to work at Wild Wally’s Warehouse for Electronics. At Wild Wally’s, the relationship between the number of digital cameras that she sells in a week (x) and her total weekly pay in dollars (y) can be represented with a linear function. In her first week at Wild Wally’s, Mickey sells 5 cameras. She earns $275 for that week. The next week, she sells 11 cameras, and her total pay for the week is $395. Determine the slope for this function?

Answer 1

Answer:

20

Step-by-step explanation:

Hello,

For two different points $(x_1,y_1)$, $(x_2,y_2)$, the slope of this function is

$\dfrac{y_2-y_1}{x_2-x_1}$

so in this example it comes

$\dfrac{395-275}{11-5}=\dfrac{120}{6}=20$

The slope of this function is 20
