if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
If you have any expression that defines a line, you can find the slope of the line. After you have found the slope of the line, you can then write an expression describing the line in slope intercept form. You can't define a slope-intercept form for any nonlinear equation, because the slope is always* changing; there are often several intercepts as well.
Linear functions can be represented by a straight line in space. One way to define a straight line uniquely is to use its slope (or direction vector) and any one point on the line.
The line perpendicular to a line with a slope of 1/5 has a slope of -5.
The instantaneous rate change of the variable y with respect to x must be the slope of the line at the point represented by that instant. However, the rate of change of x, with respect to y will be different [it will be the x/y slope, not the y/x slope]. It will be the reciprocal of the slope of the line. Also, if you have a time-distance graph the slope is the rate of chage of distance, ie speed. But, there is also the rate of change of speed - the acceleration - which is not DIRECTLY related to the slope. It is the rate at which the slope changes! So the answer, in normal circumstances, is no: they are the same. But you can define situations where they can be different.
if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
no slope.A single number does not define a line or curve and so cannot have a slope.
Slope is found by calculating rise over run. It represents the steepness of a line and the line's direction. The higher the absolute value of the slope, the more the line's steepness increases, and vice versa. If the slope is positive, the line is diagonal upwards to the right ( / ). If the slope is negative, the line is diagonal downwards to the right ( \ ). If the slope is zero, the line is horizontal. If it is "undefined", the line is a vertical line.

Positive slope: The line rises from left to right. Negative slope: The line falls from left to right. Zero slope: The line is horizontal. Undefined slope: The line is vertical.
a line with a positive slope rises from left to right
y - 7x is not an equation but an expression. It cannot, therefore, define a line.
The x is the slope of a line and the y intercept is where the line passes through the y-axis on a grid.
(3, 18), (3, 18) is just one point: it does not define a line.
Linear functions can be represented by a straight line in space. One way to define a straight line uniquely is to use its slope (or direction vector) and any one point on the line.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
Slope of a line = m slope of perpendicular line = -1/m
