The slope of a line doesn't change if you zoom in or out.
If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
The slope of a line measures the steepness of the line.
The slope is rise over run. If another line was parallel, the slope would be the same.
You cannot: the slope is not defined.
it gets larger
The coefficient of x changes as the slope changes.
it goes down
The angle that the line makes with the axes changes.
As the slope gets smaller and smaller the line gets flatter and flatter (or more horizontal).
It Gets Flatter!
It approaches a horizontal line
The line becomes more and more level (horizontal).
What do you mean? As in if you connect two points that make a horizontal line? Are you trying to figure out the Slope? The slope of a horizontal line is 0. And the slope of a vertical line is undifined. If that's what you were asking. Or if you were asking plainly what it is when that happens, it's just a horizontal line.
It gets closer to 0.
The line gets less steep.
