I am confused here, need help!

Hey, Just t be clear on Coordinate Geometry Progress Quiz #3,
Option 3 is marked as true.
But suppose, you took, x = 5, and y intercept is zero. Although product is zero, but, it doesn’t passess the origin.

So, how did you make this true. For the last option?

I think if the y-intercept is 0, the line is the x-axis. In this case it definitely passes through the origin. But I am not sure, lol

How can you take x=5, and y-intercept as 0?

If logically, if you say that the y-intercept is 0, it means that the line cuts the y-axis at y=0. Which is basically the origin itself right?

Yes, I understand your logic! you’re right, If it’s x =5, I can’t say y-intercept is zero.

Still, I am not able to understand the concept that it passes through the origin, what about y = k?

This line doesn’t have an x-intercept altogether.

So how will the product be 0?
