y=-3x-12 \r
\n" ); document.write( "\n" ); document.write( "I have to have two pairs in order to graph.. x & y intercept ..
\n" ); document.write( "(x,y) , (x,y)
\n" ); document.write( "======================
\n" ); document.write( "It's a straight line, so 2 points are needed.
\n" ); document.write( "Each pair is a point.
\n" ); document.write( "y=-3x-12
\n" ); document.write( "Pick a value for x and find y
\n" ); document.write( "x = 0, y = -12 --> (0,-12)
\n" ); document.write( "x = 2, y = -18 --> (2,-18)
\n" ); document.write( "---
\n" ); document.write( "Plot the 2 points, draw a line thru them.
\n" ); document.write( "---------
\n" ); document.write( "(0,-12) is the y-intercept
\n" ); document.write( "If you want the x-intercept, use y=0 and find x
\n" ); document.write( "y=-3x-12
\n" ); document.write( "0=-3x-12
\n" ); document.write( "x = -4 --> (-4,0)
\n" ); document.write( "----------
\n" ); document.write( "All 3 points are on the straight line.
\n" ); document.write( " \n" ); document.write( "
\n" );
