***MEDAL FOR BEST ANSWER!!***

OpenStudy (anonymous):

Input in standard form the equation of the given line. The line that passes through (-2, 4) and is parallel to x - 2y = 6

hartnn (hartnn):

can you find slope of x-2y = 6 ?

OpenStudy (anonymous):

oop looks like hartnn gots this one.

OpenStudy (anonymous):

Is it -3?

hartnn (hartnn):

no, isolate the 'y' bring it in the form of y=mx +c then m= slope

OpenStudy (anonymous):

x - 2y = 6 -x -x -2y = 6-x Is that right so far?

hartnn (hartnn):

yes, now just divide by -2

OpenStudy (anonymous):

y = -3x?

hartnn (hartnn):

y = - 3+x/2 isn't it ?

OpenStudy (anonymous):

Okay yeah I just didn't know what you do to the x when you divide by -2.

hartnn (hartnn):

ok, so the slope = m = 1/2 right ?

OpenStudy (anonymous):

Ohh yeah okay. I see that now.

hartnn (hartnn):

so, parallel lines have same slope, so for your line too, m =1/2 point =-2,4 now can you find the equation ?

OpenStudy (anonymous):

I got x - 2y = 10?

hartnn (hartnn):

correct!

OpenStudy (anonymous):

Awesome! Thanks!

hartnn (hartnn):

welcome ^_^
