Question

Hello again! Here's another question.

1. The table shows the height of a plant as it grows. What equation in slope-intercept form gives the plant's height at anytime?

Months Height
2 8
4 15
6 22
8 29

A. y=(7/2)x+1
B. y=(7/2)x+8
C. y=(7)x+1
D. y=(y)x+8

This question has been confusing me. So if anyone could help that would be great!

Answer 1

check the table. As x increases by 2, y increases by 7.

So, the slope of the line is 7/2, making the only possible choices A and B.

y = 7/2 x is 7 when x=2, but the table has y=8. So, we have to adjust things and get

y = 7/2 x + 1

(A)

If you check the other values, you will see that A works for them as well.
