add all numbers and divide by the count of numbers.
It is not.
400 decimeters = 4,000 cm
4,000 cm = 40 m

x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
