Question

Which equation is true for all x- and y- values in the table below?​

Answer 1

Put in 1 for x and which problem gives you 7

the answer is y=7x

Answer 2

Answer: The correct option is (D)
`y=7x.`

Step-by-step explanation: We are given to select the correct equation that is true for all x and y in the following table :

x 1 2 3 4

y 7 14 21 28

From the above table of values of x and y, we note the following :

`(1,7)~~~~\Rightarrow 7=7* 1,\\\\(2,14)~~~\Rightarrow 14=7*2,\\\\(3,21)~~~~\Rightarrow 21=7*3,\\\\(4,28)~~~~\Rightarrow 28=7*4.`

Therefore, we can conclude the following equation :

`y=7* x\\\\\Rightarrow y=7x.`

Thus, the correct option is (D).
