Algebra.Com's Answer #533880 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! f(x)=7 is the same as f(x)=0x+7\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That has a slope of 0.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Anything parallel to this line will also have a slope of 0.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = mx + b\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = 0x + b\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = b\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This equation must go through (4,-1). So that means b must be equal to -1 to force the y coordinate of each point to be -1.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the final answer is f(x) = -1 \n" ); document.write( " |
