Explanation:
Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.
Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.
The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.
\text{Function Rule:}
Function Rule:
V(x)=7x
V(x)=7x
Plug x=11 Into Rule:
V(11)=7(11)=77
Correct Answer:
The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.
A function relating these variables is V(x) =V(x)= 7x7x.
So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test
