Algebra.Com's Answer #435491 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! This is the same as a line with ordered pairs, (k,C) and two points are given; find the equation for the line. You are looking for C=mk+b, much like you were finding y=mx+b. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The points on this line are (1.4,40), and (1.8,50). \n" ); document.write( "Slope, m=(50-40)/(1.8-1.4)=25. \n" ); document.write( "From C=mk+b, b=C-mk. Pick a point and find b.\r \n" ); document.write( "\n" ); document.write( "b=50-25*1.8=5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Equation would then seem, C=25k+5. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If k=1.7, C cooking time predicted is C=25*1.7+5=47.5 minutes \n" ); document.write( " |
