Algebra.Com's Answer #195260 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Do it like this: \n" ); document.write( "--------------------------- \n" ); document.write( " Given 2 points example. \n" ); document.write( "Find the equation of the line thru the points (2,1) and (3,5) \n" ); document.write( "--------------------- \n" ); document.write( "This is a 2 step process. First find the slope of the line thru the points. \n" ); document.write( "slope, m = diffy/diffx \n" ); document.write( "m = (5-1)/(3-2) \n" ); document.write( "m = 4 \n" ); document.write( "--------- \n" ); document.write( "Now use y = mx + b with either point to find b, the y-intercept. \n" ); document.write( "y = mx + b \n" ); document.write( "5 = 4*3 + b \n" ); document.write( "b = -7 \n" ); document.write( "------- \n" ); document.write( "y = mx + b \n" ); document.write( "y = 4x - 7 is the answer. \n" ); document.write( "------------------------ \n" ); document.write( "For further assistance, or to check your work, email me via the thank you note. \n" ); document.write( " \n" ); document.write( " |
