Graph and compare proportional relationships
8.EE.5
Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

Find the equation of a line
8.EE.6
Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

Behold Mr. Slope Man!
1.) Positive slope (eye brow above "+" eyeball. 2.) Negative slope (eye brow above "-" eyeball. 3.) Undefined slope (vertical line for the nose, "U" is for undefined at the bottom of the nose. 4.) Zero slope (horizontal line for the mouth, "o" at the ends of the mouth are zeroes. Finding slope from a graph
