The graph of a function must be linear if it has what characteristic? It passes through the origin.
It crosses the x-axis more than once.
It crosses the y-axis exactly once
It has a constant slope.

Has a constant slope

Step-by-step explanation:

As I write this Reiner is standing at my side. He knows this is a love letter but he’s still sneaking glances. Honestly it’s no wonder the creep is still single.

That said, he did give me his word that he’d deliver this letter to you. He says he owes me for the time I doubled back to save him.

I’m sorry about that. I never would have imagined myself choosing those two over you.

I’m gonna die soon,

but I’ll die without regrets.

Or that’s what I’d like to say.

Truth is, I do have one.

It's that I never got to marry you...

With love, Ymir.

The answer is D- It has a constant slope.

Step-by-step explanation:

For this question you can use process of elimination. A function that is linear can pass through the origin, but it doesn't have to. Also a linear function can only cross the x-axis once. C could work, but a linear function isn't the only function that crosses the y-axis only once. So that leaves D. For a function to be linear it must be going in a straight line so that also means the slope will remain constant.
