The equation Ax+By=0 goes through the coordinates (-7,-4) and (14,2) What is the value of A?

A = 0

Step-by-step explanation:

System of equations

We have a general equation

Ax + By = 0

We are required to find the value of A, knowing that the ordered pairs (x,y)=(-7,-4) and (14,2) meet the condition.

Use (-7,-4):

A(-7)+B(-4)=0

Or, equivalently:

-7A-4B=0

Use (14,2):

A(14)+B(2)=0

Dividing by 2:

7A+B=0

Adding both equations:

-7A - 4B + 7A + B =0

Simplifying:

-3B = 0

B = 0

If follows that, also

A = 0

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
