Question

For which values of A, B, and C will Ax + By = C be a vertical line through the point (7, 4)?

A. A = 1, B = 0, C = 4

B. A = 0, B = 1, C = 4

C. A = 0, B = 1, C = 7

D. A = 1, B = 0, C = 7

Answer 1

Answer:

B

Step-by-step explanation:

Let's take 7,4 as x and y respectively.

Substituting it into the formula,

We have

A(7)+B(4)=C

Checking the possible answers,

A. becomes like this

1(7)+0(4)=4

7+0=4 which is wrong.

Taking B

0(7)+1(4)=4

0+4=4 which is correct therefore we go for B.

Answer 2

The correct option is B. A = 0, B = 1, C = 4

• The calculation is as follows:

Let's take 7,4 as x and y  

Now Substituting it into the formula,

 A(7)+B(4)=C

A. becomes like this

1(7)+0(4)=4

7+0=4

wrong.

B

0(7)+1(4)=4

0+4=4

4 = 4
