Question

The graph of a proportional relationship contains the point (8, 4).

What is the corresponding equation?


y=−2/1x

y=−1/2x

y=1/2x

y=2/1x
Please Help

Answer 1

y = 1/2x

Explanation:

Points are (8,4)

x = 8

x = 8y = 4

y= −2/1x

4= -2(8)

4= -16

That's wrong

y= −1/2x

4= -1/2(8)

4= -4

That's wrong

y=1/2x

4=1/2(8)

4=4

That's right

y=2/1x

4=2(8)

4=16

That's wrong

So the answer is choice C
