You can put this solution on YOUR website!
as you are given m=-3, slope/gradient=-3\r
\n" ); document.write( "\n" ); document.write( "Also m=(y-y1) / (x-x1)\r
\n" ); document.write( "\n" ); document.write( "therefore -3=y-(-2) / x-1 where y1=-2, x1=1, ie : (-2,1)\r
\n" ); document.write( "\n" ); document.write( "Cross multiply, -3(x-1)=y-(-2)\r
\n" ); document.write( "\n" ); document.write( "expand and simplify -3x+3=y+2\r
\n" ); document.write( "\n" ); document.write( "do -2 both side -3x+3-2=y+2-2\r
\n" ); document.write( "\n" ); document.write( "tidy up -3x+1=y\r
\n" ); document.write( "\n" ); document.write( "swap sides y=-3x+1\r
\n" ); document.write( "\n" ); document.write( "because the equation is in the form of y=mx+c\r
\n" ); document.write( "\n" ); document.write( "slope = co-efficient of x and intercept=c, constant\r
\n" ); document.write( "\n" ); document.write( "Again as you can see slope/gradient=-3 and intercept=1\r
\n" ); document.write( "\n" ); document.write( "I hope that answer is clear. Try doing it again and again. Also practise similar questions to understand more.\r
