ANSWER

p = -10

Step-by-step explanation

The formula for the slope of a line that passes through points (x1, y1) and (x2, y2) is:


m=(y_1-y_2)/(x_1-x_2)

In this problem we know the slope, one point and the x-coordinate of the other point. We have to find its y-coordinate:


-(3)/(2)=(p-2)/(3-(-5))

Solving for p:


\begin{gathered} -(3)/(2)=(p-2)/(3+5) \\ -(3)/(2)=(p-2)/(8) \\ p-2=-(3)/(2)\cdot8 \\ p-2=-12 \\ p=-12+2 \\ p=-10 \end{gathered}
