This makes no sense can someone explain. harold can buy 2 pounds of bananas for $7.write an equation to represent the cost c for b bananas. answer is supposed to be k(k=y/x) then write your equation as y=kx

b) well because you get well

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
