Solve for A and B, given AX+BY=-10 and (2,1) and 2x+3y=7?

Solve for A and B, given AX+BY=-10 and (2,1) and 2x+3y=7

I need an example, not the answer, that is cheating

This is an example of a system of linear equations. You have 2x + 3y = 7 and an unknow line of Ax + By = -10. However, what you know at this point is that this system is consistent meaning it has exactly one solution. The two line intersect at (2, 1). Now if you really think about this, the line that’s formed by Ax + By = -10 can be infinitely many.

One example out of many possible solutions for A and B:

A = 1

B = -12

since x =2 and y = 1

then

Ax + By = -10 -> x – 12y = 10

Now put this system together

x – 12y = -10

2x + 3y = 7

Solve them either by elimination or subsitution, you will get (2, 1)
