Question

Identify the equations as parallel lines, perpendicular lines, or neither​

Answer 1

Answer: These two lines are perpendicular.

Explanation:

The slope of -2x+3y=11 is 2/3, and the slope of 6y=4-9x is -3/2. Since 2/3 and -3/2 are opposite reciprocals, their intersection of their lines is perpendicular, or 90 degrees.
