To determine whether the two linear equations are parallel, perpendicular, or neither, let’s find the slopes of both equations.

Equation 1: y = −3x + 7

The slope () is −3.

Equation 2: 3y = −9x + 6

Solve for y: y = −3x + 2

The slope () is −3.

Comparison:

Parallel Lines: Slopes are equal. Here, = −3 and
