In this lecture you will learn the basics of Slope. Our instructor will first begin with the various possibilities of Slope values from 0 Slope, Undefined Slope, to Positive Slope and Negative Slope. You will finish with Parallel Lines and Perpendicular Lines before the four thorough examples.
The slope of a
straight line is a measure of how steep the line is. Lines that
increase as x increases have positive slopes, those that decrease as
x increases have negative slopes.
Slope is defined
to be the change in the y-coordinates of two points divided by the
change in the x-coordinates of those points.
The slope is the
same no matter which two points you pick to compute it.
A vertical line
has no slope, a horizontal line has a slope of 0.
parallel lines have the same slope, non-vertical perpendicular lines
have slopes whose product is 1.
