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).

For two ratios to form a proportion they have to be equal.
To see if two ratios are equal we express them in their simplest form.
In this case we notice that in the first ratio both numbers are multiples of five, then:
In the second case we notice that both numbers are multiples of 2, then:
Since both ratios can be simplified to the same final ratio, they form a proportion.
