Lines and slope, worked out

The Slope Grid

Straight lines on the coordinate grid, one step at a time: find the slope (rise over run), write the equation of a line, switch between its forms, graph it, and build lines that are parallel or perpendicular — with the staircase drawn on the grid and the reason for every move. Solving for x, or two equations at once? That’s on the Balance Scale.

m Slope and the line’s forms
rise Up and down, plugging in
run Left and right, × ÷ both sides
+ − Add or subtract both sides

Say it out loud

    One move per step, nothing skipped. Stuck on the fraction arithmetic inside a step? Work it on the Fraction Bar or the Number Line; solving for x is on the Balance Scale. Two lines crossing, curves, inequalities or moving shapes? Those are on the Graph Paper.
