Question

Can someone please help me with this Thanky you.

Answer 1

The answer would be 2x - y = 2

About Standard Form:

• Ax + By = C
• A & B & C are integers
• A & B are both non zero
• This form is good to use when wanting to find the x & yintercepts of a line

2x - y = 2: 2x - y = 2:

2(2) - 2 = 2 2(-1) - -4 = 2

4 - 2 = 2 -2 + 4 = 2

2 = 2 2 = 2

x + 2y = 4: x + 2y = 4:

2 + 2(2) = 4 -1 + 2(-4) = 4

2 + 4 = 4 -1 - 8 = 4

6 = 4 -9 = 4

2x + y = 2: 2x + y = 2:

2(2) + 2 = 2 2(-1) + -4 = 2

4 + 2 = 2 -2 + -4 = 2

6 = 2 -6 = 2

x - 2y = 4: x - 2y = 4:

2 - 2(2) = 4 -1 - 2(-4) = 4

2 - 4 = 4 -1 + 8 = 4

-2 = 4 7 = 4

Really really sorry if I'm incorrect...
