Tomas wants to draw a graph of resistance in ohms against length of wire in cm. Look at his grid. The y-axis is already labelled resistance in ohms and scaled from 0.0 to 5.0. The x-axis has no label and no scale, and the grid is six large squares wide. His results are: 10 cm and 0.7 ohms; 20 cm and 1.5 ohms; 30 cm and 2.0 ohms; 40 cm and 4.3 ohms; 50 cm and 3.7 ohms; 60 cm and 4.3 ohms. Write down the label that Tomas should write on the dotted line under the x-axis, including the unit, and write down the length of wire that one large square on the x-axis should represent. Write your two answers in order, separated by a comma: first the label, then the scale.
