A line has the equation x=(y/80). At which point does this line intersect the y-axis?

Show Spoiler
Answer: (-20, 0)

Explanation: x = 0 - 20, or x= -20.

0=(3/4)x-30

(3/4)x=30

x=40.

The line intersects the x-axis at (40,0).

What am I missing? This does not make sense to me, but do not seem to have an issue with other c plane PS problems.

y-intercept is for x=0, so it's (0, 0).

Thanks to both of you.

I get the y-intercept. I don't understand why the x-intercept would also not be 0.

This is the only question I remember seeing where I could calculate what both intercepts were.

That explanation is from MGMAT verbatim. Is it wrong? It should cross at (0,0) for both x and y it seemed tome.

In the MGMAT solution, you have the equation 0=(3/4)x-30, which leads me to believe that the original equation is y = (3/4)x - 30
Is that correct?

However, you wrote that the original equation is x = (y/80)

What is the original equation?

Hello,

I see that the original equation is x = (y/80) in my book - not y = (3/4)x - 30. Could someone provide insight about how to solve this equation ( x = (y/80)) to find the point where this line intersects the x-axis?
