If $850 is deducted each month for 12 months from your checking account to pay your mortgage, what impact will it have on your checking account balance?
A) $10,200
B) $850
C) -$10,200
D) -$850

C) -$10,200

Step-by-step explanation:

If a monthly deduction for a mortgage costs $850, yearly it will cost $10,200,  Thus reducing your balance by $10,200 yearly

c -10,200

Step-by-step explanation:

you multiply 850 by 12 for each month which is 10,200

then you add the negative symbol because that amount will come out of your checking

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
