Since l and m are parallel, the unlabeled angle adjacent to the 63° one also has measure (7x - 31)° (it's a pair of alternating interior angles).

Then the three angles nearest line m are supplementary so that

(7x - 31)° + 63° + (5x - 8)° = 180°

Solve for x :

(7x - 31) + 63 + (5x - 8) = 180

12x + 24 = 180

12x = 156

x = 13

The bottom-most angle labeled with measure (4y + 27)° is supplementary to the angle directly adjacent to it, so this unlabeled angle has measure 180° - (4y + 27)° = (153 - 4y)°. The interior angles of any triangle have measures that sum to 180°, so we have

(7x - 31)° + 63° + (153 - 4y)° = 180°

We know that x = 13, so 7x - 31 = 60. Then this simplifies to

123° + (153 - 4y)° = 180°

Solve for y :

123 + (153 - 4y) = 180

276 - 4y = 180

96 = 4y

y = 24

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
