Which of the following rates is proportional to $2.50 for 5 cans? A.$4.50 for 9 cans
B.$1.50 for 1 can
C.$4.00 for 7 cans
D.$2.00 for 3 cans

The answer is A. $4.50 for 9 cans

Step-by-step explanation:

Divide 2.50 by 5 and you get $0.50 a can

Multiply $0.50 by each of your answers

A. 0.50 times 9 = 4.50

B. 0.50 times 1 = 0.50

C. 0.50 times 7 = 3.50

D. 0.50 times = 1.50

As you can see A. is the only one that matches

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
