The standard form of a line:

A x + B y = C

where:

A is a positive integer

B and C are integers

1.

2 x = - 5 y + 2

Add 5 y to both sides

2 x + 5 y = 2

2.

y = - 3 x + 7

Add 3 x to both sides

3 x + y = 7

3.

7 - 3 x + 4 y = 0

Subtract 7 to both sides

- 3 x + 4 y = - 7

Multiply both sides by - 1

3 x - 4 y = 7
