Step-by-step explanation:
The point of intersection is found by equating the expressions for P:
6d = 5d +15
d = 15
p = 6d = 6·15 = 90
The point of intersection of the graphs is (15, 90).
The first equation graphs as a line with slope 6 through the origin.
The second equation graphs as a line with slope 5 through point (0, 15).
It is inconvenient to graph p and d using the same scale, so the attache graph has the vertical scale compressed somewhat.
