You can put this solution on YOUR website!
Y=5X-7 (RED LINE)
\n" ); document.write( "THIS LINE HAS A SLOPE OF 5 & A Y INTERCEPT OF (0,-7)
\n" ); document.write( "TO FIND ANOTHER POINT SET Y=0 & SOLVE FOR X
\n" ); document.write( "0=5X-7
\n" ); document.write( "5X=7
\n" ); document.write( "X=7/5 WHICH IS THE X INTERCEPT (7/5,0)
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Y-5X=8 (GREEN LINE)
\n" ); document.write( "Y=5X+8 HERE WE ALSO HAVE A SLOPE OF 5 WITH A Y INTERCEPT OF(0,8)
\n" ); document.write( "TO FIND ANOTHER POINT. SET Y=O & SOLVE FOR X
\n" ); document.write( "0=5X+8
\n" ); document.write( "5X=-8
\n" ); document.write( "X=-8/5 WHICH IS THE Y INTERCEPT (-8/5,0)
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+5x+-7%2C+y+=+5x+%2B8%29+\" (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 5x -7 and y = 5x +8).
\n" ); document.write( "----------------------------------------------------------------
\n" ); document.write( "so I'm just wondering if the answer would be 1.5, 0.5 or 0.5, 1.5
\n" ); document.write( "I think it's 1.5, 0.5 could you tell me if I'm correct?
\n" ); document.write( "-----------------------------------------------------------------
\n" ); document.write( "THERE IS NO SOLUTION TO THESE 2 LINES VIA GRAPHING BECAUSE THEY DO NOT INTERSECT.
\n" ); document.write( "THERE IS ALSO NO ALGEBRAIC SOLUTION:
\n" ); document.write( "Y=5X-7 USING (5X-7) FOR Y IN THE OTHER EQUATION PROVES THIS POINT:
\n" ); document.write( "(5X-7)-5X=8
\n" ); document.write( "5X-5X=8+7
\n" ); document.write( "0=15 IS NOT A SOLUTION.
