Question

The coordinate grid shows the plot of four equations
Which set of equations has (1, 4) as its solution?

A and D
B and D
A and C
B and C

Answer 1

If you look at the point (1,4), only two lines go through it.

Lines B and Lines D pass through points (1,4)

Your answer is B) B and D.

Answer 2

your answer is B and D because it both goes through 1 and 4. and as a matter of fact they both intersect each other.
A can't be because it's -3 and +4.  
C can't be because it's 4 and 3. 
so that leaves us with B and D.
B is 1 and 4 and D is 1 and 4 but they both intersect each other.
the graph is just playing you or tricking you that's all.
