Answer:
(0,0),(-4,6)
<em></em>
Explanation:
Given
Coordinates: (0,0) to (4,6)
Required
Reflect over the y axis
Represent the initial coordinate with (a,b)
When reflect over y axis, the new coordinate becomes

In this case

The reflected coordinate becomes 
<em>Hence, the coordinates of the reflected line is (0,0),(-4,6)</em>
Over the past million years, Earth's globally averaged surface temperature has risen and fallen by about 5˚C in ice-age cycles, roughly every 100,000 years or so (Figure 2.1a).
The more direct sunlight an area receives the warmer the temperatures will be, while the indirect sun rays on a certain area cause cooler/colder temperatures.
