What is the slope of line n?

2

Step-by-step explanation:

2 - 1            1

  =         =    2

1 - 1/2         .5

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
