The midway line has the same slope and a y-intercept halfway between 1 and −3: (1 + (−3))/2 = −1.

Common wrong answers

If you answered 1

1 is the y-intercept of the first line.

If you answered 2

2 is the slope.

If you answered -2

−2 is half of −4, the difference of the intercepts, not their average.
