Answer 1

The table and graph doesn’t match so , the table and the graph isn’t proportional.


I would go with only the graph is proportional



Hope this helps

Answer 2

B both are proportional

Explanation:

so i think by proportional its linear?

so the graph is linear because its a line and its a function, but for the table we first have to find the slope by using the equation

y2 - y1 / x2 - x1

(4, 1.31) and (8, 2.62) will be the points we will use

2.62 - 1.31 / 8 - 4

1.31/4

0.3275x

now i think we use a point we did not use yet sooo (16, 5.24)

we substitute

y = 0.3275x + b

5.24 = 0.3275(16) + b

5.24 = 5.24 + b

b = 0

so the equation would be

y = 0.3275x

now we check with the last point given

6.55 = 0.3275(20) ?

6.55 = 6.55

so i think the answer is both are proportional ?
