A single value for x and a single value for y represent a point, not a line. A point cannot have a slope.

That line is horizontal on the graph. Its slope is zero.
That line is horizontal on the graph. Its slope is zero.
Slope = zero. The line is horizontal, parallel to the x-axis.
The slope of the line y = -2 is zero.
No.Unless the slope is zero, every line will extend from minus infinity to plus infinity. So part of it will be negative and part positive.No.Unless the slope is zero, every line will extend from minus infinity to plus infinity.

Slope = zero. The line is horizontal, parallel to the x-axis.
The function y = 2/17x has a slope = -2/17x2 so that for each value of x (other than zero) it has a different slope. Near x = zero its slope approaches + or - infinity, while for large x it approaches zero.
If the equation of a line is [ Y = -2 ] the the line is horizontal. Its slope is zero.
The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
Zero. Y=4 is a horizontal line.
The slope (or gradient) of a vertical or horizontal line is zero.
The slope of the line y = -2 is zero.
if they are parallel they run side by side forever and will never cross. if they are perpendicular they will cross at a 90 degree angle. You can also tell just by looking at the equations for the lines if they are in the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). When two lines are parallel, they have the same slope. When two lines are perpendicular, the slope of one is the negative reciprocal of the slope of other. For example, a line with a slope of 2 is perpendicular to a line with a slope of -½, and a line with a slope of 1 is perpendicular to a line with a slope of -1. (y = 1 and x = 1 are perpendicular because the slope of y = 1 is zero, the slope of x = 1 is infinity, the reciprocal of infinity is zero, and negative zero equals zero.)
