The slope intercept form is y=mx+b where b is the y-intercept and m is the slope
y=-3x+b
substituting in the point (-4,-6)
-6=12+b
b=-18
so our equation is y=-3x-18
we can also solve by using the slope point formula
y-y1=m(x-x1)
y+6=-3(x+4)
y+6=-3x-12
y=-3x-18 which is the same as our first answer

The correct answer is C. Finance charge

Explanation:

A credit card is a service offered by financial entities such as banks that allows customers to buy goods and pay them later. This implies the customer does not immediately for goods but pays for these after a specific time. The use of this benefit implies related costs such as fees for the use of the credit card, and interest costs (money charged for borrowing the money from the bank), which are known as finance charge or the money charged for the benefit of using credit. According to this, the correct answer is C.
