Write the lines in slope-intercept form and state whether they are parallel, perpendicular, or neither. 7y - 4x = -7
-4x + 7y = 16
A) Parallel
B) Perpendicular
C) Neither

Question

Quizplus · Accepted Answer

Both equations can be rewritten in slope-intercept form (y = mx + b) as follows: For the first equation, 7y - 4x = -7 becomes y = (4/7)x - 1, and the second equation, -4x + 7y = 16, becomes y = (4/7)x + (16/7). Since both lines have the same slope (4/7) but different y-intercepts, they are parallel.
