Answer:
When you find the gradient (slope) of a graph, you divide a change of value on the vertical-axis (the 'rise') by a change of value on the horizontal axis (the 'run').
Gradient = rise/run.
The vertical axis has units of cm, so the rise in in cm.
The horizontal axis has units of 1/grams = g⁻¹, so the rise is in g⁻¹.
units for slip are
rise/run ≡ cm/g⁻¹ ≡ cm.g
