This is how you proceed for slopeintercept equations. From the graph, read off the yintercept (=10). Read off the slope (about 15). Check the 4 options to see which one satisfies both conditions. If you can use help reading off the slope and intercept, please post.

no. Yintercept is where the curve (line in this case) intersects the yaxis. Can you read it off?

so the y intercept is where you have the curved line?

isnt the intercept 10 though?

mathmate Group TitleBest ResponseYou've already chosen the best response.1
Right, yintercept is 10. Did you find the slope?

would the answer be D?

mathmate Group TitleBest ResponseYou've already chosen the best response.1
Your answer D is correct. You have eliminated A and B because the yintercepts there are zero. Good job. Between C and D, the difference is the slope. The graph shows that y increases from 10 to 14 between 0 and 1. This implies a slope of (1410)/(10)=4. Therefore answer D is correct.
