Question

11. Which two lines are parallel?
1. 5y = 2x - 5
2. 5y = -4+ 3x
3. 5y - 3x = -1

Answer 1

Parallel lines must have the same slope as they do not cross. The slope is determined by the value before x. 1 and 2 are parallel necause both have 3x slope. (Third line is -3x but if you move it to other side as it should be, it will be 3x)
