Are the lines 7x - 4y = 3 and x - 4y = 3 parallel, perpendicular, or neither

7x - 4y = 3

subtract 7x from each side

-4y = - 7x + 3

divide by - 4

y = 7/4 x - 3/4

slope is 7/4

x - 4y = 3

subtract x from each side

-4y = -x + 3

divide by - 4

y = - 1/-4x

y = 1/4 x - 3/4

since the slopes are not the same (parallel) nor negative reciprocals (perpendicular) they are neither

Answer: neither
