1. ## y=mx+b???

Okay on my homework it says:
Use the graph to write the equation for the line.

(there is blank graphs for all problems)

8a. (0,-2/7)

this is the one that really got me...
8c. (0,-2) 8d. (0,-2)

Wouldn't it be the same answer?

they want me to put it in y=mx+b form. But i do not understand the double problems.

Thanks for anyone that can help me.

In order to develop an equation for a line, we at least need a point and slope or two points. We have to know the direction of the line. One point will not do.

So, if your graph is blank, then you cannot tell what the slope is or another point the line might go through, so we can go no further. Make sure you're not overlooking something in the text.
