Which of the following lines goes downwards from left to right?

O y = 2x + 5

O y=2x-6

O y = 2x

O y=-2x + 20

D

Step-by-step 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
