Write an equation of the line containing the given point and parallel to the given line.
Express your answer in the form y=mx+b.
(8,9); x+7y=2
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The solution in the post by @mananth is INCORRECT.
See my correct solution below.
The original equation/line is
x + 7y = 2
Find the slope of this line
7y = -1x + 2
Divide by 7
y = + .
The slope is m = .
The slope of a line parallel to the above line will be the same
The slope of the required line will be . <<<---=== not -0.14, as @mananth mistakenly states !
m= , point (8,9)
Find b by plugging the values of m & the point in
y = mx + b
9 = + b
b = 10
m =
Plug value of the slope and b
The required equation is y = + 10. ANSWER
Solved.
----------------------------
Not only this particular problem is solved incorrectly by @mananth.
Many other similar problems were solved incorrectly by @mananth.
Incorrectly solved are ALL similar problem, where coefficients of linear equations
are / (should be) rational numbers, which can not be presented as finite decimal fractions.
Then @mananth, by applying his incorrect algorithm of rounding, makes everything wrong.
Rounding in such situations IS NOT ALLOWED.
