A line contains the points (-3, -2) and (7,2). 1. Without doing any calculations, determine whether the slope of this line is positive or negative.
Explain or show your reasoning
2. Calculate the slope of the line.

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.
