PLease hurry! i need it! And the testing thing is happening, so before 6 pm?

x = 9 and y = 6 ==> (9,6)

Since we we are look for the y-value/coordinate, it is 6.

Step-by-step explanation:

-x + 3y = 9

y =  x

Can be written as:

-x + 3y = 9

 x + y = 0

Now we solve:

-1(-x + 3y = 9) = x - 3y = -9

3(  x + y = 0) = -2x + 3y = 0

We now get:

x - 3y = -9

-2x + 3y = 0

We can now eliminate one of the values (-3y and 3y)

x - 3y = -9

-2x + 3y = 0

-x = -9

/-1   /-1  

x = 9

Now we solve for y using one of our original equations (either one is fine)

-x + 3y = 9

-9 + 3y = 9

+9        + 9

3y = 18

/3     /3

y = 6

This is how we got our final answer (9,6)

Hope that helps!

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
