Solve for x in the second equation.
Just add 1 to both sides to get x = 9y + 1
Then plug 9y + 1 into the first equation for x
7(9y+1) - 9y = 1
63y + 7 - 9y = 1
54y + 7 = 1
54y = -6
y = -6/54 or -1/9
Plug y back into one of the equations to get x = 0
Answer: (0, -1/9)
Answer:
-42
Step-by-step explanation:
Cross multiply
5 * -2 = -10
8 * 4 = 32
-10 - 32 = -42

Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span>

--- (1)
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' =

--- (2)
As (1) = (2), hence the lines are parallel and their slope is

(Option A).
