x=2 is a vertical line going through (2,0) its slope is undefined.
y=9 is a horizontal line going through (0,9) its slope is 0.
Vertical and horizontal lines are PERPENDICULAR to each other, they meet at a 90 degree angle.
Happy Calculating!!!

QUESTION:



IS THIS A PERPENDICULAR LINE, PARALLEL LINE, OR NEITHER OF THOSE TWO LINES. X=2, Y=9



ANSWER:

Given equations are X = 2 and Y = 9

First of all rewrite the equations in terms of x as follows,

X = 2 ==> Y = X - 2 ---------------(1)

and Y = 9 -----------------------------(2)


\Now give arbitrary values to X in equation (1) and find corresponding values of Y.

that is ,

If x = 0 , y = 0-2 = -2


If x = 1 , y = 1-2 = -1


If x = 2 , y = 2-2 = 0

If x = 3 , y = 3- 2 = 1 and so on..........

For the second equation, for all values of x, value of y will be 9.


Now plot graph using these points.

Then the graph comes like this,



+graph%28+700%2C+700%2C+-15%2C+15%2C+-15%2C+15%2C+x-2%2C+9%29+




The graph shows that the lines are neither parellel nor perpendicular.



Hope you understood.
