Answer:

Lines 1 and 2 are parallel because they have the same slope

Step-by-step explanation:

slope of line 1 = 1/2

slope of line 2 = 1/2

slope of line 3 = 4

slope of line 4 = 14

how to find slope of line 2, solve for 'y':

x - 2y = -1

-2y = x - 1

y = 1/2x + 2

how to find slope of line 4, simplify for 'y':

y + 3 = 1/4x - 1/4(6)

y = 1/4x - 6/4 - 3

y = 1/4x -6/4 - 12/4

y = 1/4x - 18/4
