    Is this an EXACT drawing of the graph? It has to be exact

    i think the slope might be -2

    Ok... So to find the slope, you need to look at the points. Find two points, these points should go through the x and y axis. What you're gonna do to find the slope is rise over run (rise / run) this'll give you a fraction, so for instance in this graph, you'll see the line

    Do you see how the line goes up 1 point and then 2 to the right?

    Alright great, so now you have to look at the line and see where it crosses exactly. In your graph, the line goes down 4 and to the right 2. Do you see how I got those numbers?

    That's the slope. So the since it goes down 4, that would be -4 over 2. Simplify and you get -2, so you're right :)
