Answer:

D

Explanation:

A line with a positive slope goes upwards from left to right.

A line with a negative slope goes downwards from left to right.

The given lines are all in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 5 has m = 2 ← positive

y = 2x - 6 has m = 2 ← positive

y = 2x has m = 2 ← positive

y = - 2x + 20 has m = - 2 ← negative

Thus y = - 2x + 20 goes downwards from left to right
