Consider two lines.
Line 1 contains the points (3, 5) and (-1, 5). Line 2 contains the points (2, 4) and (2, 1).
One of these lines is vertical and one is horizontal.
One of these lines has a slope of 0 and the other has an undefined slope.
Calculate the slope of each line and classify as vertical or horizontal.
Remember that slope is "rise over run"

slope of l1=(5-5)/(-1-3)=0
slope of l2=(1-4)/(2-2)=-3/0=indeterminate
the lines are perpendicular
l1-horizontal
l2 vertical

Simply take the difference of the y coordinates (rise) over the difference in the x coordinates (run) to determine the slopes:
Line 1: (5-5)/(-1-3) = 0/-4 = 0
Line 2: (1-4)/(2-2) = -3/0 = undefined
0 = ( rises not at all over an change in x) = horizontal
undefined = (rises over no change in x) = vertical

5-5 over 3+1= 0 over 4 this line's slope is 0 and it is the horizontal
line 2 4-1 over 0 this lines solpe is undefined and it is the vertical
remember: if zero is on top than the slope is zero, but if the zero is on the bottom than the slope is undefined
hope this helps, but next time try

Let function f(x): y=mx
m=y/x : slope
using two points on a line:
m=(y2-y1)/(x2-x1)
Line 1:
P1: (3,5); P2: (-1,5)
m=(5-5)/(-1-3) = 0/-4 = 0 => Horizontal Line
Line 2:
P1: (2,4); P2: (2,1)
m=(1-4)/(2-2) = -3/0 = Undefined => Vertical Line

the points with the same y value is horizontal, hence, (3,5) and (-1,5) is a horizontal line.
The points with the same x value is vertical, hence, (2,4) and (2,1) is a vertical line.
slope of the horizontal line
m=(Y2-Y1)/(X2-X1)
m= (5-5)/(1-3)
m= 0/-2
m= 0
slope of the vertical line
m=(Y2-Y1)/(X2-X1)
m= (1-4)/(2-2)
m= -3/0
m= undefined

For increasing cubic binomials the final formulation is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

When in doubt, draw a picture.
Get some graph paper or make your own sketch
and it will all be totally clear.
