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.
