Question

The graph below shows the survey results for a group of students who were asked how many honors classes they have taken and how many elective classes: How many elective classes would a student likely have taken if he or she has taken 12 honors classes? 15, because y = one halfx + 9 12, because y = y = negative one halfx + 9 6, because y = one halfx + 9 3, because y = negative one halfx + 9

Answer 1

the other person is correct! C:

Explanation:

Answer 2

3, because
`y=-(1)/(2)x+9`.

Explanation:

Looking at this graph, we can start to determine the equation for it.

The y-intercept of this graph is 9, therefore there will be a constant of 9.

We can find the slope by looking at rise over run. It vertically travels -1 for every 2 horizontally. So the slope is
`-(1)/(2)`.

Making this into an equation gets us
`y=-(1)/(2)x+9`.

Now we can substitute 12 into this equation as x.

`y=-(1)/(2)(12)+9\\ y=-6+9\\y=3`

Hope this helped!
