i know that they change around the questions... so, i wrote down the question and answer just in case. i really hope this helps anyone!! :)
there are some questions that i was told by my teacher that had different options from what is listed. meaning that some people have completely different answers than others on some questions. im not 100% sure if everyone's is like this, but if yours is ill write those down on the bottom.
now the answers...
1. for the data in the table, does y vary directly with x? if it does, write an equation for the direct variation
x y
8 13
16 26
24 39
a- yes;y=1.625x
2. for the data in the table, does y vary directly with x? if it does, write an equation for the direct variation
x y
32 24
16 8
8 6
a- no; y does not vary directly with x
3. the grade a student earns on a test varies directly with the amount of time the student spends studying, suppose a student spends 6.5 hrs studying and makes a grade of 84% on the test. what is an equation that relates the grade earned on a test, g, with the amount of time spent studying, t, in hrs? what is the graph of your equation?
(the graphs are a little harder to explain, hope you get what im trying to say)
a- the graph ends on (6, 70) its pointed more up than the others
4. match the equation with its graph
y= 3/4x - 2
a- its the only line that passes through the bottom-right coordinate block
5. match the equation with its graph
-2x + 7y = 14
a- the left part of the line only goes a tinny-bit into the bottom-left coordinate block.
6. express the relationship between distances and the time in simplified form as a unit rate. determine which statement correctly interprets this relationship.
a- mine was 58/1 but i did see some other people that had 46/1
7. find the slope of the line.
a- 1/5
8. what is the slope of the line that passes through the pair of points (1,7) and (10,1)
a- 2/3
im lowkey tired asf its literally 4:50 am where i live in texas rn...so im going to sleep buuuut ill try to finish up with the answers tmrw/later today with a different post. hope this doesn't affect anyone until I'm back
