Hi,
You can start by eliminating option A and B because a line is increasing if it goes up from left to right. So now the options are C and D. Then you look at the constant which is +1 or -1. This number is your y-intercept so if you look at the graph, you can see that the graph goes through the y axis at (0,-1). So the answer is D. y=3x-1.

1)
for a valid triangle two sides added together have to always be larger than the third
(otherwise it turns into a line)

12, 18, 6 would not be a valid triangle, because 12+6<=18
but 12, 18, 14 would be valid, because
12+18>14
12+14>18
18+14>12

2)lets start with an obvious right triangle and have the axis along the y and x axis like
so decide some x like -4 and some y like -3 and keep all other coordinates at 0:
A=(-4,0) B=(0,-3) and C=(0,0)

make it a bit more complicated (less 0s) by some x and y translation like (-2,3)
just add that to every point's coordinates and you get

A=(-6,3), B=(-2,0), C=(-2,3)

If a trend line has a slope of -3, what is true about the data? Select all that apply.

Answer: Choice B and choice D

--------------------------------------------------------

A negative slope indicates that the line moves downward as you move from left to right. As x increases, y decreases (and vice versa). There's this opposite relationship going on.
