Which of the following is an irrational number?
A. π
Answer: Option (3)
Step-by-step explanation:
The slope of the given line is

Thus, the answer must be Option (3)
Slope = (2 + 1) / (-5 - 10) = -3/15 = - 1/5
Equation
y - 2 = -1/5 (x + 5)
y - 2 = -1/5 x - 1
y = -1/5 x + 1
Answer
y = -1/5 x + 1
Since that angle all together is 180, 100 is 2z-10 and z is 55
