Determine whether AB and MN are parallel, perpendicular, or neither. Graph each line to verify your A(-2,-7). B(4,2), M(-2, 0), N(2,6)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the answer is 2/54
