Parallel and Perpendicular Equations of Lines

Write the equation of a line PARALLEL to y = 2x + 3 that passes through the point (3, 1).

Write the equation of a line PERPENDICULAR to y = -2x + 1 that passes through the point (2, 3).

Write the equation of a line PARALLEL to 3x - y = 2 that passes through the point (1, 5).

Which statement correctly describes the graph?

• The lines are parallel because they have different slopes.

• The lines are NOT parallel because they have different y-intercepts.

• The lines are parallel since they have the same slope and different y-intercepts.

• The lines are perpendicular.

Write the equation of the line that is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?
