I have to linear equations(adsbygoogle = window.adsbygoogle || []).push({});

3x + 2y =7 and -6x + 6y= 6

when expressed as linear combination in column vector form they become:

x[3,-6] + y[2,6] = [7,6]

when solving this linear combination graphically ,First vector is plotted

like this x=3, y=-6 and second vector is plotted like x=2, y=6 as per

textbook

1) first vector contains x coeffceints of equation 1 and 2. I am consfused why second element of first vector(-6) is plotted on y axis. It is x element as per equation 2. Please clarify on this why this done like

this?
