D: no; y does not vary directly with x
D: graph; positive slope, y-intercept -1
A: graph; positive slope, y-intercept 4

C: 1/4
D: -1/2
C: undefined
D: y-2=3(x-5)
C: y+6=-5/8(x+10)
B: y-21=7(x-3)
B: x-intercept -4
B: 5x+8y=24
A: y=2x+2
C: neither
C: perpendicular
D: y-9=-3/7(x+4)
D: the function have the same shape. The y-intercept of y=|x| is 0, and the y-intercept of the second function is -5
C: the two graphs have the same shape but the second graph is shifted 2 units down.
B: y-intercept -3
C: x-intercept 3
D: no correlation
