Graph linear equations: fill the table, plot the points
Now the real job. For each rule: put every x into the formula and write the output in the table. Press Check the table. Then plot every row as a point on the grid and press Check my points. Two of the rules are written with y and two with f(x). Same job either way. Check your tables with a spreadsheet if you like.
Look at your dotsIn every one of these four graphs, the dots line up. Put a ruler on them and you will see it. Next lesson: why a rule like y = 2x − 1 always makes a straight line, and why any x you can think of, even 1.5 or −37, lands on that same line.
