    Can you find the slope of the line?

    \[\text{Slope} = \frac{\text{rise}}{\text{run}} = \frac{\Delta y}{\Delta x}\]

    No, that's your y-intercept.

    Which, in your equation (in the form \(y = mx + b\)), is \(b\).

    So you've figured out your y-intercept. Now all you need is the slope. To figure this out, find any two points on the graph. Calculate the change in y and the change in x needed to get to the other point. The points indicated on the graph are convenient, because they both fall directly on whole numbers.

    I got it wrong anyhow. I thought it was C-questioned myself and chose D. Anyhow it was wrong and I still do not understand it. Thanks for trying to help me.

    What are you still stuck on? Can you calculate the slope?

    It's not nice to post the same question twice.
