Here are the equations of four lines.
Two of the lines are parallel.
Which lines?
Line 1 2y = 8x + 6
Line 2 x + y = 6
Line 3 4x - y = 5
Line 4 4x + 2y = 1

Respuesta :

Answer:

Line 1     2y = 8x + 6    y = 8/2 x + 6 = 4 x + 6     slope = 4

Line 3    4x - y = 5       y = 4 x -5                         slope = 4

Step-by-step explanation:

y = mx + b       m: slope

Line 1     2y = 8x + 6    y = 8/2 x + 6 = 4 x + 6     slope = 4

Line 3    4x - y = 5       y = 4 x -5                         slope = 4

parallel lines have same slope
