When you reflect something across the y axis, you take the opposite of all the x axis coordinates (the point 'on the other side of the number line,' and when they add together, they make 0). Now we can solve for each of the points.
Reflected across the y axis, we have to take the opposite of -2 and that's 2. That means that P becomes P'(2, -4).
Reflected across the y axis, we have to take the opposite of -3, and that's 3. That means that Q becomes Q'(3, -1).
Reflected across the y axis, we have to take the opposite of -4 and that's 4. That means that R becomes R'(4, -4)
The association between the given lines is that they are 'neither perpendicular nor parallel.'
To prove, let's convert the given equations in their slope-intercept form i.e. 'y = mx + b'
-7x + 2y = 3
2y = 7x + 3
y = 7/2x + 3/2
-6x + 3y = 2
3y = 6x + 2
y = 2x + 2/3
This shows that both the lines have different slopes, as well as, intercepts of y. And,
= 2 * 7/2 ≠ -1
Thus, it is not perpendicular also.
Therefore, <u>option D</u> i.e. 'neither perpendicular nor parallel' is the correct answer.
