Answer:
B: The independent variable (x) is the amount of time Daniel consults. The dependent variable (y) is the amount, in dollars, Daniel earns for a consultation.
Daniel charges a one-time fee of $95 (this is when x=0), so the y-intercept is 95. Daniel earns $70 for each hour he works, so the slope is 70.
Step-by-step explanation:
A first order function in the following format:
[tex]y = ax + b[/tex]
Has this proprieties:
In this problem, we have that:
[tex]y = 70x + 95[/tex].
x is the number of hours of a consultation.
y is the amount that Daniel earns for a consultation.
Dependent variable: y
Independent variable: x
y-intercept is 95
slope is 70
The correct answer is:
B: The independent variable (x) is the amount of time Daniel consults. The dependent variable (y) is the amount, in dollars, Daniel earns for a consultation.
Daniel charges a one-time fee of $95 (this is when x=0), so the y-intercept is 95. Daniel earns $70 for each hour he works, so the slope is 70.
