You're right because it's a scientific or try to plug that number into a scientific calculator.
Answer:
y = -2
Step-by-step explanation:
The line that is perpendicular to y-axis will be a horizontal line so it's slope is 0 => y = 0x + b or y = b
Using (5,-2) => -2 = b => b = -2
then y = -2

n(D) = 4
Step-by-step explanation:
Given Data:
Set D = {4, 6, 8, 10}
The number of elements in a set is called the cardinal elements (or) cardinality of the sets. This is denoted by n(A).
Here it is denoted by n(D).
The number of elements in the set D is 4.
The cardinality of the set is 4.
Hence, n(D) = 4.
