Question

What is the equation of the line

Answer 1

Hello there!


The answer is B.
`(2)/(7)`
-----------------------------------------------------------------------------------------------------

Explanation and Work:



We first must identify if the line goes through the origin or not.

The origin is (0, 0)

The line does go through the origin. This means that there is no y-intercept

The specific equation we would you use would be:

y = kx

K is the constant

We find this by finding the slope.

Slope is found by:


`(y2 - y1)/(x2 - x1)`

y2 = 2

y1 = 0

x2 = 7

x1 = 0

Now, let's plug in these numbers.


`(2-0)/(7-0) = (2)/(7)`

So, now let's plug he slope into our formula.

y =
`(2)/(7) x`

So, our answer would be B.


I hope I helped!
