Alexandra works at a digital marketing agency. She has a base salary of $200 per week. Additionally, for every online campaign she manages, she earns $15 In her first month, Alexandra managed a total of 20 campaigns. If she wants to represent her weekly earnings with a linear function, f of x is equal to m x plus b where f of x is her total earnings and x is the number of campaigns she manages, what will be the slope m and the y -intercept values?
Answer
A
m is equal to 200 and b is equal to 15
B
m is equal to 15 and b is equal to 200
C
m is equal to 200 and b is equal to 20
D
m is equal to 20 and b is equal to 200
Explanation
In the linear function f(x) = mx + b, the slope m is how much earnings increase for each campaign. Alexandra earns $15 per campaign, so m = 15. The y-intercept b is her base salary when she manages zero campaigns, which is $200; therefore, choice B is correct.
