Algebra.Com's Answer #775365 by Theo(13342) You can put this solution on YOUR website! the formula, as i understand it is: \n" ); document.write( "y = 98 - 16/5x. \n" ); document.write( "i read it to mean: \n" ); document.write( "y = 98 - 16/5 * x \n" ); document.write( "parentheses would have made this more clear. \n" ); document.write( "something like y = 98 - (16/5) * x would do. \n" ); document.write( "if it were 98 - 16 / (5x) then it would be wrong because, when x = 0, the result would be undefined because you can't divide by 0 and get a real number as an answer. \n" ); document.write( "so, ..... \n" ); document.write( "i'm assuming you mean y = 98 - 16.5 * x \n" ); document.write( "when x = 0, y = 98. \n" ); document.write( "that's your y intercept because the definition of the y-intercept is the value of y when x = 0. \n" ); document.write( "based on that, your solution should be selection A. \n" ); document.write( " \n" ); document.write( " |
