Write a system of equations that has 2 lines that intersect at (-3,7) and have (-3,7) as a solution and show me how to solve it.

\n" ); document.write( "We can choose the slopes then use the point slope formula; y-y1 = m(x-x1)
\n" ); document.write( "slope of the 1st line m=3
\n" ); document.write( "y - 7 = 3(x - (-3))
\n" ); document.write( "y - 7 = 3(x + 3)
\n" ); document.write( "y - 7 = 3x + 9
\n" ); document.write( "y = 3x + 9 + 7
\n" ); document.write( "y = 3x + 16, 1st line equation
