Graphing, worked out

The Graph Paper

Everything on the coordinate plane, one step at a time: plot and read points, find distances and midpoints, fill tables of values, graph functions and find their key features, solve systems and inequalities by graphing, move shapes around, and fit a trend line to a scatter plot — with the reason for every move. Just straight lines and slope? That’s on the Slope Grid.

Say it out loud

    Drag a graph to move around it; use + and − to zoom. Exact answers are worked out with fractions, and a graph gives an estimate when a point falls between the grid lines. Straight lines in depth are on the Slope Grid, solving by algebra on the Balance Scale, and one-variable data on the Dot Plot.
