Expert Answer:

The V-I graph is a straight line, and it's slope represents the resistance.

If temperature increases, resistance increases, hence the straight line will be more steeper, i.e. it'll move towards y axis/V axis.

It'll be opposite if temperature decreases, since then resistance will decrease.
