Question

Determine whether the following lines are parallel, perpendicular, or the same line.
y = 3x – 4 and y – 3 = 3( x + 1)

A. Parallel

B. Perpendicular

C. Same Line

D. None of these

Answer 1

solve the 2nd for "y", what do you get?

Answer 2

y = 3x – 4 --------- I

y – 3 = 3( x + 1)
y - 3 = 3x + 3
y = 3x + 3 + 3
y = 3x + 6 --------- II
Since both I and II have same slope but different y-intercepts, so they will be parallel lines
