What is the equation of the line that is perpendicular to the given line and psses through the point (5,3)?

 y= -1/a*x+5/a+3

Step-by-step explanation:

The equation of given line isn't known. Let it be y=ax+b (1)

So the equation of required line is y=-1/a*x+c                     (2)

Lets put 5 instead x and 3 instead y in (2) and find c

-1/a*5+c=3

c=3+5/a

The required equation is y= -1/a*x+5/a+3

5x+2=5x+5

For Bruce, 5 represents the number of boxes, and the 2 represents the number of tiles he used from the box.

For Felicia, 5 represents the 5 boxes she used, and the other 5 is used for the tiles she bought on her own.
