write an equation of the line containing the given point and parallel to the given line
(4,-9);2x-5y=7

Question

anonymous · Answer

Get Y free to on side.. And then you find the slope.. Use it for build a Equation of the given point..

anonymous · Answer

$$2x-5y=7$$
$$y=(2x-7)\div5$$
$$y=2x \div5-7\div5$$

And the slope is then 2\5..
k=2.5 ,  and x =4 , y =-9
Use it : Y=kx+m

anonymous · Answer

will give....m = 53\5

anonymous · Answer

Equation is then... y=2.5x-53\5

amistre64 · Answer

slope can be remembered as -a/b  which in this equations is:

-2/-5  = 2/5

anonymous · Answer

Sry forgott the "\"

amistre64 · Answer

the short cut to a parallel line equation is to just plug in your values of (x,y) = get the "new" answer, for example:

2x-5y=7  ; (x=4,y=-9)

2(4) -5(-9) = ?

8 +45 = 53

"new" equation for PARALLEL line is:

2x -5y = 53 ;(4,-9)

anonymous · Answer

ahh. even shorter way thx...  iam Used to work with y=kx+m .

amistre64 · Answer

i used the y=mx+b as well, but after so many times, I noticed this pattern :)

I am gonna go over! to Ax+by=C
