Question

The table below shows the values of y for different values of x:

Which equation shows the relationship between x and y?
Ox = 5y
Oy = 5 + x
Ox = 5+y
Oy = 5x

Answer 1

y = 5x

Explanation:

x = 0 --> y = 0

x = 1 --> y = 5*1 = 5

x = 2 --> y = 5*2 = 10

x = 3 --> y = 5*3 = 15

Answer 2

y = 5x

Explanation:

You can check which is the correct answer by verifying if the options render true mathematical statements for all pair (x,y).

We notice that only the last option checks true for all four pairs of the table:

for x = 0, then
`y=5*(0)=0`

for x = 1, then
`y=5*(1)=5`

for x = 2, then
`y=5*(2)=10`

for x = 3, then
`y=5*(3)=15`

while the other functions don't give true statements for all y values.
