Points: (0, 6) and (6,0) and the slope of the line works out as -1
The slope is -1.
Slope = (8 - 0)/(0 - 4) = -2
Points: (0, 0) and (2, 6) Slope: 3
Points: (0, 0) and (4, 1) Slope: 1/4
The slope of a line refers to how steep the line is. Given two points, (x1,y1) and (x2,y2), the slope can be found by this formula: (y2-y1) / (x2-x1). If the number is positive, the line goes up. If the slope is negative, the line goes down. If the slope is zero, the line is horizontal and if the slope is undefined because the denominator is 0, the line is vertical.
If you mean: y = -4x then the slope is -4 and there is no y intercept because the line cuts through the origin at (0, 0)
y = - 4x - 9
it is 0
The slope is zero.
Slope = (8 - 0)/(0 - 4) = -2
Points: (0, 0) and (2, 6) Slope: 3
The slope is 0.
y = 0. You can get this from the slope-intercept equation of the line.
Points: (0, 0) and (4, 1) Slope: 1/4

You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.

If the slope is negative, the line goes down. If the slope is zero, the line is horizontal and if the slope is undefined because the denominator is 0, the line is vertical.
If the original slope is 0, then the opposite reciprocal of 0 is still 0. Oops! Reciprocal of 0 (n/0) is undefined! A vertical line has undefined slope, the horizontal line has slope of 0.
