Are the lines - 6x + 3y = -9 and y + 1 = -3(x + 2) parallel,
perpendicular, or neither?

Step-by-step explanation:

Given lines:

To determine the answer we need to compare slopes of the lines.

Parallel lines have same slopes, perpendicular lines have negative-reciprocal slopes.

Let's put them in slope-intercept form:

As we see the slopes are 2 and -3, so the lines are neither parallel nor perpendicular
