y = 4x - 5
Is a line that has a slope of 4 and has a y-intercept of -5.
When we say slope, it means the tangent of the angle the line make with the x axis. In our case the tangent is 4. The angle whose tangent is 4 is about 76 degrees. So the line makes an angle of 76 degrees to the x-axis and intersects the y-axis at point with coordinates 0, -5

Is y equals negative one a function why or why not?
It depends on what the domain and the range are. If the range is the positive integers, then the mapping is not even defined.

What would a mapping diagram for 3x plus 2 be?
It would be a straight line with gradient 3, which would intercept the y axis at the point (0,2).

How do you solve int of x sq plus int of y sq equals 1 -- I need to sketch the region?
I assume that Int(x) represents the integer part of the number x. This is not a function since it is a many-to-many mapping. If it is a real valued mapping, the domain is at most [-1, 1] When x = -1 or x = 1, then y is in [0, 1); When x is in (-1, 1), then y is in [1, sqrt(2)).
What does y equals 9x equals 3 equal?

What is the answer for y equals x?
x equals y
Is x2-y2 equals 81 a function?
The answer, for y as a function of x, depends on the range of y. Over the real numbers, it is not a function because a function cannot be one-to-many. But it is always possible to define the domain and range in such a way that the mapping in not one-to-many.
