Answer:
D. Negative.
Step-by-step explanation:
In truth, when given the graph you don't really need to use the points, but if needed it you would use the formula:
y-y₁=m(x-x₁)
Plug in your information and solve.
-1 - 5 = m (2 - (-1))
-6 = m (3)
-6 = 3m
m = -6 / 3
m = -2
(m = slope)
Also, when shown on the graph =
If the slope is going:
up from left to right: it's positive
down from left to right: it's negative
straight up and down (vertical): it's undefined
straight left to right (horizontal): it's zero.
Angle B corresponds to angle D, therefore they are equal. To find Angle B's length, add the two known angle measures then subtract the sum from 180. (All angle measures in a triangle equal 180 when added)
32 + 41 = 73
180 - 73 = 107
<h3>Answer:</h3>
<u>Angle B = </u><u>107º </u>
