Which of the following angles are congregant

see explanation

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

11

5x - y + 6 = 0 ( subtract 6 from both sides )

5x - y = - 6 ← in standard form

12

y + 1 = 2(x - 3) ← distribute parenthesis

y + 1 = 2x - 6 ( subtract y from both sides )

1 = 2x - y - 6 ( add 6 to both sides )

7 = 2x - y, thus

2x - y = 7 ← in standard form
