Question 1017406
5x-2y=3
10x-4y=6
Rewrite
-2y=-5x+3
y=(5x/2)-(3/2)
-------------
-4y=-10x+6
y=(5x/2)-(3/2)
---------------
These have an infinite number of solutions.  The answer if B, and standard form is how the equation appears above.
They are the same equation.  The bottom equation is the top one multiplied by 2.
{{{graph(300,200,-10,10,-10,10,(5x/2)-(3/2))}}}
Because the two are the same, you don't want an ordered pair, which is a common point of intersection.  You want an equation of a line.  The graph shows that line.  It is both equations.
