Thank you so much for your help . I appreciate your time:)I was wondering if this is also
\n" ); document.write( "correct: y=3.5(2)^(x/2) ????
\n" ); document.write( "This is not correct because you have a power (^) factor & a fraction (x/2).
\n" ); document.write( "-----------------------------------------------------------------------------
\n" ); document.write( "(-2,3.5)
\n" ); document.write( "(0,7)
\n" ); document.write( "(7-3.5)/(-2-0)
\n" ); document.write( "3.5/-2
\n" ); document.write( "-1.75 for the slope of this line.
\n" ); document.write( "14=2*-1.75+b is the equation with a slope of -1.75 through the points (2,14).
\n" ); document.write( "14=-3.5+b
\n" ); document.write( "14+3.5=b
\n" ); document.write( "b=17.5 the y intercept.
\n" ); document.write( "Thus the line equation is:
\n" ); document.write( "y=-1.75x+17.5
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+15%2C+-10%2C+20%2C+-1.75x+%2B17.5%29+\" (graph 300x200 pixels, x from -6 to 15, y from -10 to 20, -1.75x +17.5). \n" ); document.write( "
\n" );
