Answer 1

I can't see the images you attached. Could you either

- upload the four graphs again, or
- describe each one briefly (e.g. "straight line sloping up", "vertical line", "parabola opening up", "circle centered at (1,2)"),

and I’ll pick which graph represents a linear function.

Tip: A graph represents a linear function if it is a straight line that is not vertical. (A horizontal line y = b is linear; a vertical line x = a is not a function.)
