Algebra.Com's Answer #3103 by Abbey(339)![]() ![]() ![]() You can put this solution on YOUR website! find the slope by taking the difference of the y values/difference of x values: \n" ); document.write( "(y-y1)/(x-x1) \n" ); document.write( "(0-(-4))/(3-0) = 4/3\r \n" ); document.write( "\n" ); document.write( "find the intercept by plugging one of these points and the slope into the equation y=mx+b \n" ); document.write( "0=(4/3)*3+b \n" ); document.write( "0=4+b \n" ); document.write( "b=-4\r \n" ); document.write( "\n" ); document.write( "then the formula is \n" ); document.write( "y=mx+b \n" ); document.write( "y=(4/3)x -4 \n" ); document.write( " \n" ); document.write( " |
