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

3. krissywatts

i think the slope might be -2

4. krissywatts

i'll try to out up a better one

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

6. ddiez

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?

9. krissywatts

yes

10. krissywatts

i had to pick those lines also so im not sure if i picked the right line or not lol

11. ddiez

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 :)

And nah, there's no such thing as picking a wrong line :P
