first is out, graph is going down when it should be going up

6. satellite73

fourth is out for the same reason

7. satellite73

second looks good you have $$(1,4)$$ on the graph and $$2\times 2^1=4$$

8. satellite73

also $$(2,8)$$ is on the graph, and $$2\times 2^2=8$$ so i would go with the second option

9. ikshjbdckoj

y = –2 · 5x

10. ikshjbdckoj

this is for the second graph.
