Matt has $471.60 in his checking account and feels he's doing pretty well financially. then his car stops running. his mechanic is able to fix it in a day, but with the towing charges, parts, and mechanic's labor, he now needs to pay the service center $624.11 so he can drive his car to work. of the following choices, which is the best course of action for matt? a) pay the service center with his visa credit card b) pay the service center with his mastercard debit card c) write a check for $624.11 and hope the service center doesn't take it to the bank before next payday d) call his employer to say he won't be able to come to work

the answer would be A. Since he currently doesn't have enough fund within his ban account using a credit card is advised greatly. Credit cards are good for emergencies like his case. it allows the holder to be able to purchase the items needed without immediate pay, but he would still end up paying the amount he used plus some probable interest due to possible interest rate in the card company.

Step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
