You may be right about this TDS,No, dependence does not mean that only one variable "matters"
It implies that the second variable (R) is a function of the temperature(t)
The graph would show R(t) where t is the written along the horizontal axis, and R along the vertical.
I had a go at my chem book, looking for similar phrasing of similar relationships, and I saw that the structure that uses "depends" was preferred over "dependence"
"As you can see the resistance depends on the temperature. This reveals... "
I think that this is just a matter of personal preference.
