The slope within two sets of points is calculated using the slope equation 
<h3>What is slope?</h3>
The slope of a line or points is the rate of change of the line.
This in other words means that, the vertical change per unit horizontal change
Assume that the points are given as:
(x1, y1) and (x2, y2)
The slope (m) of the points is:

Hence, the equation of two sets of points is

I don’t think this exact answer is there
Answer: the numbers were negative so he needed to add the positive numbers to that equation (I think sorry if I’m wrong)
Step-by-step explanation:
Answer:
54
Step-by-step explanation:
angle A+angle B+Angle C =180 degree [ angle sum property of a triangle]
36 +90 + angle B =180 degree
126 +angle B =180 degree
angle B= 180-126
54 degree
