Algebra.Com's Answer #155460 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! A straight line L passes though the point (0,-1) and is parallel to the straight line y=3x+1. \n" ); document.write( "------------- \n" ); document.write( "The slope, m, of the line y=3x+1 is 3. \n" ); document.write( "------------ \n" ); document.write( "i. Write down the equation of the straight line L. \n" ); document.write( "Use (always): \n" ); document.write( "y-y1 = m*(x-x1) (x1,y1) is the point (0,-1) \n" ); document.write( "y+1 = 3x \n" ); document.write( "y = 3x-1 is the line L. \n" ); document.write( "ii. Given that L passes through the point (2,b) find the value of b. \n" ); document.write( "y = 3x-1 \n" ); document.write( "x = 2 \n" ); document.write( "y = 5 = b \n" ); document.write( " \n" ); document.write( " |
