You can put this solution on YOUR website!
You are almost right. You made a couple of very small errors, which I have corrected below for you. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I have done slope -1 and (2, -1).
\n" ); document.write( "form f(x) =ax+b
\n" ); document.write( "a= -1
\n" ); document.write( "f(x) = -1
\n" ); document.write( "Since f(2)=-1
\n" ); document.write( "f(2)= -1(2)+b
\n" ); document.write( "-1=-2+b
\n" ); document.write( "-1+2=b
\n" ); document.write( "1=b
\n" ); document.write( "f(t) = -1t+1 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, check it! The slope is indeed -1.
\n" ); document.write( "f(2)= -1(2) + 1 = -2 +1 = -1, as it should be.\r
