Answer:

-1/6

Step-by-step explanation:

First find the slope of the line through the points

m = (y2-y1)/(x2-x1)

= (-4-8)/(1-3)

= -12/-2

Now we need to find the slope of the line that is perpendicular

Perpendicular lines multiply to -1

6 * mp = -1

mp = -1/6

Answer:

y = 100°

Step-by-step explanation:

x = 40° (vertical angles are congruent)

y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.

According to the exterior angle of a triangle, thus:

y = 40 + 60

y = 100°
