You can put this solution on YOUR website!
The given slope is m = 7. The line goes through (-1,8) which means x = -1 and y = 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we have these three pieces of info:
\n" ); document.write( "m = 7
\n" ); document.write( "x = -1
\n" ); document.write( "y = 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We will plug those three pieces of info into y = mx+b then solve for b.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = mx+b
\n" ); document.write( "8 = 7*(-1)+b
\n" ); document.write( "8 = -7+b
\n" ); document.write( "8+7 = -7+b+7
\n" ); document.write( "15 = b
\n" ); document.write( "b = 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the y intercept is b = 15.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Because m = 7 and b = 15, this means y = mx+b turns into y = 7x + 15 which is the final answer. \n" ); document.write( "
\n" );
