d(5/4 -1/2

Answer 2

Does D. contain fractions?

Answer 3

yes

Answer 4

This question falls into the same category that we did before. Let's start with A (-2,4)
Can you try plugging in -2 for x and 4 for y?

Answer 5

ok 3(-2) +2 (4)=2

Answer 6

Now try solving. What is 3*-2 and 2*4?

3*-2= -6

Answer 8

2*4 = 8

Answer 9

Good. Now, does \[-6 + 8 = 2?\]

Answer 10

yes

Answer 11

Very nice. Try plugging in -2 for x and 4 for y, in the next part: \[-2x + y = 8\] and solve

Answer 12

-2(-2) +4=8

Answer 13

ok -2*-2=4 4+4 = 8

Answer 14

so its right can you check like one or two more with me

Answer 15

this is easy

Answer 16

yeah i just want to be correct :T

Answer 17
