Alright so this is what you do.
You need to isolate one variable so that it is y = or x =
Lets go with y = for the first one
-x +3y = -6
x - 3y = 6
Isolate y = by adding x for the first one and then subtracting x from the second one.
3y = -6 + x
-3y = 6 - x
You would then divide the second one by -3 and divide by 3 in the first one.
y = (-6 +x) / 3
y = (6 -x) / -3
Since this is what y = you can put them together.
-6+x) / 3 = 6-x)/-3 (I put one parenthesis for convenience)
This equation is now set and you aren't done yet.
You can take out -1 from each side. This makes it no solution since you must always multiply by -1.
(6+x) / 3 = -1( (6+x) / 3)
Try the second one on your own!

Answer:
(b) 4x- 3y = 6
Step-by-step explanation:
Standard form is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0. (If a=0, then b>0.)
__
A: slope-intercept form with variables on both sides of the equal sign.
B: standard form
C: coefficients aren't integers
D: coefficients aren't integers; leading coefficient is negative.
Answer:
Step-by-step explanation:
Let the point P is at the origin (0, 0).
Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.
Rule for the dilation of a point by a scale factor = k
(x, y) → (kx, ky)
If k = 
Then, A(8, 4) → A'(4, 2)
B(-2, 2) → B'(-1, 1)
C(4, -4) → C'(2, -2)
Now we can plot the new image with points A', B' and C'
Answer:
3) B
4) D
5) C
Step-by-step explanation:
3) Slope is before X
4) Set equal to Y
5) Use rise over run to find slope then find y intercept
No she is not correct as 43 is a prime number. It is an odd number though.
