Question

I need help please?!!!

Answer 1

yes

Explanation:

To determine if the ordered pair is a solution to the equation.

Substitute the x and y values into the left side of the equation and if equal to the right side then the pair are a solution

3x - 2y = 3(- 2) - 2(- 8) = - 6 + 16 = 10

Hence (- 2, - 8) is a solution to the equation

Answer 2

Yes

Explanation:

3 x - 2 y = 10

( - 2 , - 8 )

We know that coordinates are put in the form ( x , y ) and from that we can work out that x = -2 and y = -8

Now we just substitute x = -2 and y = -8 into 3 x - 2 y = 10

3 x - 2 y = 10

{ 3 × ( - 2 ) } - { 2 × ( - 8 ) } = 10

{ - 6 } - { - 16 } = 10

- 6 + 16 = 10 True
