In Asha's science experiment, her bacteria are dying at a constant rate of 600 an hour. If she drew a graph of the number of bacteria in her culture where  represented the time in minutes since the start of the experiment and  represented the number of bacteria remaining in the colony, her graph would be a line. What would be the slope of this line?

Given P(10,12) and Q(20,36), find the coordinates of a point whose distance from both P and Q is exactly 13.

1:- slope is rate of change

2:- Notice that $\overline{PQ}=26$ by distance formula, hence the point is the midpoint, or $(15,24)$.
