Answer:

Lines A and B are parallel

Explanations:

The slope-intercept form of the equation of a line is given as:

y = mx + c

where m represents the slope

and c represents the y-inercept

Two lines are parallel if they have the same slope

Considering the given lines one after the other:

For line A: y = 2x + 3

The slope, m = 2, the y-intercept, c = 3

For line B: y = 2x - 5

The slope, m = 2, the y-intercept, c = -5

For line C: y = -2x + 3

The slope, m = -2, the y-intercept, c = 3

The two lines that have the same slope, m = 2 are the parallel lines.

That is, line A; y = 2x + 3 and line B: y = 2x - 5 are parallel.
