Algebra.Com's Answer #96338 by checkley71(8403) ![]() You can put this solution on YOUR website! (8,3)(-2,1) FIRST YOU NEED TO FIND THE SLOPE (Y2-Y1)/(X2-X1) \n" ); document.write( "(1-3)/(-2-8) \n" ); document.write( "-2/-10 \n" ); document.write( "1/5 OR .2 FOR THE SLOPE. \n" ); document.write( "NOW USING THE LINE EQUATION [Y=mX+b] REPLACE X & Y WITH ONWE SET OF COORDINATES. \n" ); document.write( "3=.2*8+b \n" ); document.write( "3=1.6+b \n" ); document.write( "b=3-1.6 \n" ); document.write( "b=1.4 THE Y INTERCEPT. \n" ); document.write( "Y=.2X+1.4 STANDARD LINE FORMULA FOR THIS LINE. \n" ); document.write( " \n" ); document.write( " |
