When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
Answer:
The water dispenser's capacity in liters is 20liters
Explanation:
Given:
A water dispenser capacity = 20,000milliliters
To find
the capacity of the water dispenser in liters
To determine the capacity in liters, we will convert the capacity in ml to liters using the conversion:
1000ml = 1 liter
let the capacity of the water dispenser in Liters = y
The water dispenser's capacity in liters is 20liters
