Best ResponseYou've already chosen the best response.0i have this: y=9x/11 +44

Best ResponseYou've already chosen the best response.1your yintercept value will be a fraction...maybe you didn't multiply the 9/11 when expanding

Best ResponseYou've already chosen the best response.1\[1+y = \frac{1}{11}(459x)\]probably screwed up bringing the 1 across

Best ResponseYou've already chosen the best response.0so if i bring it to the other side it must be subtracted from the 45

Best ResponseYou've already chosen the best response.1\[y=\frac{9}{11}x+\frac{45}{11}1=\frac{9}{11}x+\frac{34}{11}\]

Best ResponseYou've already chosen the best response.1subtract 11/11 from each side: \[y+1  11/11 = \frac{1}{11}{45119x}\]\[y = \frac{1}{11}(349x)\]\[y = \frac{9x}{11}+\frac{34}{11}\]

Best ResponseYou've already chosen the best response.1well, that in fact is the equation of a line parallel to the original line, passing through 5,1 as you can see in this graph:

Best ResponseYou've already chosen the best response.1Check the rules for entry. Maybe you are entering the fractions incorrectly or maybe you are not supposed to write y = or maybe they want the equation in some other form besides slopeintercept form.

Best ResponseYou've already chosen the best response.1Maybe you want to try 9x+11y=34

Best ResponseYou've already chosen the best response.1I'll sometimes multiply by the denominator of the fraction, do the problem without the pesky fractions and accompanying mistakes, then divide again by the former denominator for the final answer.

Best ResponseYou've already chosen the best response.1I'd say you know what you're doing, in any case...watch for those fraction mistakes :)
