volume of the box? *
- 5ft cubed
- 71/2 ft cubed
- 3 ft cubed
- 7 ft cubed

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
