This question is also based on Arrhenius equation

Now  check qualitative relation in Temperature and k value
As T increase ,rate constant increases because of higher frequency of collisions.

However slope of the line is -Ea/R means if activation energy is high then rate constant is low and rate of the reaction is low.
This Arrhenius equation is proving mathematically.  But we also know that high activation energy means less molecules can cross the activation energy barrier and less rate of the reaction means less rate constant.   Check Maxwell Boltzmann curve
