I thought I’d start something new and provide some of my “corny” math tips that I provide to my students. Here’s one that helps me remember the equations for horizontal and vertical lines, and can be found in the Coordinate System and Graphing Lines section:
Horizontal lines are when “y = a number”; for example, “y = 5” (with no “x” in the equation) is a horizontal line where y equals 5. The slope is zero (0), since 0x means there is no x. You can remember this since a “y” looks like an upside down “h”, and “h” is the beginning of the word “horizontal”. The line “y = 0” sits on the x axis.
Vertical lines are when “x = a number”; for example, “x = –2″ (with no “y” in the equation) is a vertical line where x equals –2. The slope is undefined, like the line is falling from the sky. You can remember this since you can draw a “v” in an “x”, and “v” is the beginning of the word “vertical”. The line “x = 0” sits on the y axis.
Getting upwards of 300 new hits a week; at least the numbers are going in the right direction!
Have fun with math and keep reading!
