Which table of values can be defined by the function y = -2x + 5? X у -1 - 2 -1 --3 o -5 -7 1 2. -9 X V у --10-25 -5 -15 0 -5 5

x = 4 and x = - 9
In both cases the angles inside the parallel lines are same sided interior angles
24x - 1 + 20x + 5 = 180
44x + 4 = 180 (subtract 4 from both sides )
44x = 176 ( divide both sides by 44 )
x = = 4
Similarly
x + 109 + x + 89 = 180
2x + 198 = 180 ( subtract 198 from both sides )
2x = - 18
x = = - 9
