HELP O WELL Tom is also in Mr. Greene's class. One day Tom spent six hours studying. Using the class ratio of 3 to 2 from Mr. Greene's survey, which proportion can be used to find the number of hours, x, that Tom spent on the Internet? Hours on Internet Hours Studying 100 6 A. 3 2 B. 3 2 - 6 3 6 r 2 D. 2 6 3

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

whew you’re speaking a different language
