A perfect square is a number made by squaring a whole number.
Since
numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that
therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.

Answer:
y = + 2
Step-by-step explanation:
The y-intercept of the line is (0,2)
The slope of the line is
We derive the slope of a line by dividing the change in y by the change in x
So,
=
y - 2 =
The equation of the line therefore is;
y = + 2
