What is the equation of the line
konstantin123 [22]
Hello there!


The answer is B. \frac{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:

\frac{y2 - y1}{x2 - x1} 

y2 = 2

y1 = 0

x2 = 7

x1 = 0

Now, let's plug in these numbers.

\frac{2-0}{7-0} =  \frac{2}{7}

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

y = \frac{2}{7} x

So, our answer would be B.


I hope I helped!

Kim drives 156 miles from Rotherham to London.
masya89 [10]
No. See, you can take 60 out of 156 twice and you are left with 36. This means the drive would take about 2 hours and 36 minuets. 7+2=9 30+36=66 so then you add an our the time and you get that she would arrive a few minuets afterwards. (I'm sorry if I didn't explain this very well)
