Step-by-step explanation:
Answer:
x = 4 - 1 = 3
Step-by-step explanation:
2(4 - y) + 3y = 9
8 - 2y + 3y =9
8 + y = 9
y = 1

New cost of jacket =
New costs of skirt = .
Answer:
a
Step-by-step explanation:
Recall that the "point-slope" form of a linear equation may be expressed as
y = mx + b,
where m is the gradient.
If m is negative, the gradient is negative.
If m is positive, the gradient is positive.
In our case, if we consider option A,
x + 3y = -2 (rearranging)
3y = -x -2
y = (-1/3) x - (2/3)
if we compare this to the general equation at the top, we can see that
gradient, = m = (-1/3) which is negative.
hence option a has a negative gradient.
