Answer 2

@iGreen @amistre64

Answer 3

x > -3 x < -3 y > -3 y < -3

Answer 4

for starters, what is the equation of a vertical line?

Answer 5

looks like 10 and -8?

Answer 6

x = k is the form of a line that is vertical ...

so in this case, we have an x equality something, right?

Answer 7

right @amistre64

Answer 8

so the only question is: is the shading to the left or right of the x line?

Answer 9

right? @amistre64

Answer 10

to the left

so x is less than the line

Answer 11

i see so x > -3 is the answer?

Answer 12

no, the solution set is not greater than -3

its less than (to the left of) -3

all solutions for x are << that way from -3

Answer 13

so this? x < -3

Answer 14

yep

@amistre64

Answer 19

i'm choosing C

Answer 20

@iGreen help asap please!? I think It's C

Answer 21

test an obvious point, like the origin (since it is clearly in the shaded region) if that point provides a true result, then that narrows down the options.

0,0 is a good test simply because it wipes out one side completely

0 < 7
0 > 7
0 < -7
or none of them
