Can you find the slope of the line?

anonymous · Answer

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

anonymous · Answer

1/2

anonymous · Answer

No, that's your y-intercept.

anonymous · Answer

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

anonymous · Answer

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.

anonymous · Answer

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

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