Find an equation of the line. PLEASE HELP

Do you have an idea of how to solve this?

OpenStudy (unicornpoopcookies):

not at all I keep getting it wrong its driving me insane!!!!!

OpenStudy (shadowlegendx):

Through (-3, -9); parallel to 2x + 3y= 5

OpenStudy (unicornpoopcookies):

So I know I must make it in mx plus b form

OpenStudy (unicornpoopcookies):

so I subtract -2x from both sides

OpenStudy (shadowlegendx):

First thing we have to do is get 2x + 3y = 5 into slope intercept form. 2x + 3y = 5 We basically have to get y = something 2x + 3y = 5 Subtract 2x from both sides 3y = -2x + 5 Divide both sides by 3 y = -2x/3 + 5/3 Now, we know that this line passes through points (-3, -9) with -3 being the x and -9 being the y. It also tells us that this line is parallel to 2x + 3y = 5. We solved for it, and we now have the slope which is -2/3. Now we use point slope form. That is... \[y - y _{1} = m(x - x _{1})\]

OpenStudy (shadowlegendx):

Parallel means that both lines have the same slope btw. |dw:1445146669352:dw| They rise and fall at the same slope, thus they are parallel.

OpenStudy (unicornpoopcookies):

Yeah I know if i get the slope of one i found the same as the other.

OpenStudy (unicornpoopcookies):

I get the y equalls mx plus 6 right just not the other step
