Graphing Steps Lab
Build a line one step at a time: plot the y-intercept, step out with the slope, then draw the line. Generate a fresh line whenever you like.
1 Graphing Steps Lab
Press the steps in order and watch a line get built: intercept first, slope staircase second, straightedge third.
Press “New line” to begin.
A random line appears with each “New line”.
2 What to notice
Three experiments.
1. Intercept first, always
Step 1 never fails: (0, b) is one plotted point for free, no arithmetic.
2. The staircase is exact
Step 2 moves exactly run units across and rise units up — landing on a second lattice point.
3. Only step 3 draws
Until the straightedge step, you have dots, not a line. Linear means straight — no freehand curves.
