Which equation would have a graph that is parallel to the following equation? Answers choices in photo

Why is it right?

D

Step-by-step explanation:

"Parallel" means the lines have the same slope- the fractions need to be equivalent. This almost means if it's negative, like in this case, the slope must be negative. 4/6 is equal to 2/3 and is negative like the one shown.

Option C. Y= 4/6x + 6

Step-by-step explanation:

Same slope

160000

Step-by-step explanation:

Let the cost price = x

At the end of the first price, it loses ten percent = 0.9x

At the end of the second year, it loses an extra ten = 0.9(0.9x)= 0.81x

0.81x=129600

x=160000
