Answer 6

OMG, all three are correct answers

Answer 7

Wait. So will (3, 1/2).

There's no difference between either line. They intersect everywhere.

Answer 9

Yeah I just realized that lol

Answer 10

Can you help with this one please?

Answer 11

(-2,-1) and (4,10) both are N

Answer 12

Can you explain it to me please?

Answer 13

(-2,-1): -2 is x, and -1 is y. Plug in the two values and solve. (-1) = 2(-2) - 18

Answer 14

SO, i have to plug in (-2,-1) into both equtions and it had to work to be a solution and the same for (4,10)

Answer 15

Yep

Answer 16

Thank you so much I apperciate it I understand now!!

Answer 17

Another way to do this is to put y = 2x - 18 into 3x + 2y = -8. Solve for x and y.

Since they are both lines, they can only intersect at one point unless they are on top of each other. If that point matches either of the points given in the problem, you know your answer. If that point matches neither of the points in the problem, you also know your answer.

Answer 18

and what methods can I use out of these
Complete the Square Method
Substitution Method
Elimination Method
Square Root Method
Graphing Method

Answer 19

I know I can use Graphing, substitution how about the rest?

Answer 20

You can also use completing the square and elimination method to do this.

Answer 21

You can use elimination, graphing, or substitution. This isn't a quadratic equation, so there is no square to complete. Likewise, there is no square root.

Answer 22

Whoops
