Pls me asap for 6 and 7 ! (show workkk! ) + lots of points

6. 30 miles every 2 hours is the same as 15 miles every hour. When you multiply 15 miles by the number of hours (t), you find the distance. Therefore, the answer is d = 15t

7.  3 pounds of onions cost 2.67, so if you divide 2.67 by 3, you will have .89 for every pound. Now you multiply .89 by 4 and 5, since those are the only pounds in the answer choices, and see if they match. .89 * 4 = 3.56 and .89 * 5 = 4.45. C is the only one that matches, since 4.45 / 5 = .89

For number 6, we know that Amber rides 30 miles in 2 hours, so she rides 15 miles in one hour. As a result, I have this equation which is d=15t which is B. For number 7, to find the proportional in 3 pounds at $2.67, so I just need to find how much does it cost to buy one pounds of onion which equal $0.89, now I just take $0.89×5 which equal $4.45 for 5 pounds, so to find the proportional between the two of them which $4.45/5 pounds which is C. Hope it help!

B.the point lies directly on the regression
