No it is not always a mixed number if you add two mixed numbers
Essentially, you can always tell a thing's position by 3 coordinates. We also say that our world is three-dimentional: it has three dimensions -that's why three coordinates are needed. If something is on a flat surface, you know its one coordinate (all points on the same surface have the same coordinate) so you only need two more (you can call them vertical and horizontal)
Answer: 2
Formula for cube is x^3 = 8
2^3 = 8
The answer is y= -1
When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b
"m" is the slope, and "b" is the y-intercept.
Let's replace those in the function.
y = 0*x - 1
0 multiplied by anything is 0
y = 0 - 1
y = -1
