Lesson 3-4: SLOPE of lines
Today we talked about the slope of a line.
The slope of a line is its constant rate of change. It is the ratio of the vertical displacement to the horizontal displacement between any two points on the line. Note: Slope is a real number!
Parallel lines will always have equal slopes.
If two lines are perpendicular, then the product of their slopes equals -1. This translates into: the slope of one of the lines is the opposite reciprocal of the line perpendicular to it.
If the line is graphed on the coordinate plane, and we identify 2 distinct points on it, we can find the slope with a formula...which I would love to post, but this blog is unfortunately anti-math symbols! argh! I need to consult with a blog professional. To be continued...
Have a fabulous weekend! See you at the game!
