I dont think my answer is correct pls help me out

Let us solve all the given 4 equations using the table , the equation which satisfies the conditions will be correct according to the table , We will use the relation x = -3, when y = 13 , which means if we put the value of x as -3 , we should get the value of y = 13 ,

➲ Solving for A) y = 3x:

‎ㅤ‎ㅤ‎ㅤ➙ y = 3x

‎ㅤ‎ㅤ‎ㅤ➙ y = 3 × -3

‎ㅤ‎ㅤ‎ㅤ➙ y = -9

This equation is not correct !

➲ Solving for B ) y = 6x + 4:

‎ㅤ‎ㅤ‎ㅤ➙ y = 6x +4

‎ㅤ‎ㅤ‎ㅤ➙ y = 6 × ( -3 ) + 4

‎ㅤ‎ㅤ‎ㅤ➙ y = -18 +4

‎ㅤ‎ㅤ‎ㅤ➙ y = -14

This equation is not correct!

➲ Solving for C) y = -3x + 4:

‎ㅤ‎ㅤ‎ㅤ➙ y = 3x +4

‎ㅤ‎ㅤ‎ㅤ➙ y = -3 × ( -3 ) +4

‎ㅤ‎ㅤ‎ㅤ➙ y = 9 + 4

‎ㅤ‎ㅤ‎ㅤ➙ y = 14

This equation is correct !

➲ Solving for D ) y =-3x:

‎ㅤ‎ㅤ‎ㅤ➙ y = -3x

‎ㅤ‎ㅤ‎ㅤ➙ y = -3 × ( -3 )

‎ㅤ‎ㅤ‎ㅤ➙ y = 9

This one is not correct!

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~Hence, the correct answer is C) y = -3x +4

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

is this part of a question or something
