Identify the graphed linear equation

You don't have a shown equation, but I could say the process.

Where does the line intersect on the y axis? That's the y intercept. Say it's at two: your Y = mx + b equation would look like this:

y = mx + 2

You have the y intercept, so now count. The slope is rise over run: So count up, then over. (unless it's negative, then down then over.) Now you have the slope. Say it's 1/2:

y = 1/2x + 2.

That would be your linear equation! Plug in from there.

Sorry if you already know this, I just want to help!

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
