The slope of 9x11y=2 is 9/11 So plug that slope and the given point into pointslope form: \[yy _{1}=m(xx _{1})\]

@mathcalculus you did your algebra incorrectly, it appears...

can you point it out where?

i have this: y=9x/11 +44

your yintercept value will be a fraction...maybe you didn't multiply the 9/11 when expanding

@whpalmer4 i'm not sure where I have made my mistake.

\[1+y = \frac{1}{11}(459x)\]probably screwed up bringing the 1 across

isn't y (1) a y+1?

so if i bring it to the other side it must be subtracted from the 45

\[y=\frac{9}{11}x+\frac{45}{11}1=\frac{9}{11}x+\frac{34}{11}\]

subtract 11/11 from each side: \[y+1  11/11 = \frac{1}{11}{45119x}\]\[y = \frac{1}{11}(349x)\]\[y = \frac{9x}{11}+\frac{34}{11}\]

i think it's the website, it must be correct. thank you everyone.

well, 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:

Check 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.

yes, I checked. appreciate the help

it must be correct, even the calculator shows it.

Maybe you want to try 9x+11y=34

I'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.

I'd say you know what you're doing, in any case...watch for those fraction mistakes :)
