By the end of this unit: You will be able to demonstrate that you have developed the ability to:
Derive the equation y = mx + b for a line given two distinct non-vertical points (8.EE.5)
Derive the equation y = mx + b for line through the origin and the equation y = mx + b for a line intersecting the vertical axis at b (8.EE.6)
Explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane using similar triangles (8.EE.6)
Slope of a Line: In skiing, slope refers to a slanted mountain side. The steeper the slope is, the higher its difficulty rating will be. In math, slope defines the “slant” of a line. The larger the absolute value of the slope is, the “steeper”, or more vertical the line will be.
Linear Equations: • Linear equations have constant slope • For a line on a coordinate plane, to find the slope we use the ratio: rise over run
Rise is the number of units • moved up or down • Run is the number of units • moved right or left
Slope can be… positive negative zero undefined

X – Intercept • Where the line crosses the x-axis • Y = 0
y – Intercept • Where the line crosses the y-axis • X = 0
