1. What is an equation for the line with slope 2/3 and y-intercept 9?
2. What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1).
3. For the equation -4y = 8x, what is the constant of variation?
4. Suppose y varies directly with x, and y = 24 when x=8. What is the value of y when x = 10?
Please help, I don't understand any of this?

Guys, you need to understand that the answers change on the quiz. There are different question sets that are provided for the quiz, you have to do a little bit of work to match it up yourselves. This will decipher which answers are on your test.
Really anonymous got me wrong %*#$@%
Anonymous is correct y’all
yooo anonymous is correct 6/6 100% tank u
anonymous is correct I got them all right... don't listen to really anonymous those are wrong
D
C
B
B
C
D
So who is correct??
1) A
2) D
3) B
4) B
5) C
6) D
really anonymous is wrong. Anonymous is right
anonymous is still right!!
Really Anomous is correct the other all lies
Anonymous is 100% correct i got a 6/6
Anonymous is correct
Anonymous is very much not correct he will gat you 66
I just took the test and the answers are actually...
1. B- 8.5
2. A-9.4
3. C- (1,1)
4. A- -2
5. D- 4/3
6. B- -2
7. D- 2X-5
8. B- 30
9. C- y=2/3x + 9
People on here are so immature with lieing about which ones are the right answers grow up and dont purposefully make someone fail a test school sucks as it is dont make it worse I hope this helps
#1. remember the slope-intercept form?
y = mx+b
#2. The slope is (1+3)/(3-1) = 2
So, the point-slope form is
y-1 = 2(x-3)
Now rearrange that into slope-intercept form.
#3 -4y = 8x
so, y = -2x
for the equation y = kx, k is the constant of variation
#4. y = kx, so y/x = k, a constant. Thus, you want y such that
y/10 = 24/3
If you really don't understand any of this, you need to see your teacher, review the text, or google the topic and read the many examples online.
