## About "HOY and VUX worksheet"

In the webpage "HOY and VUX worksheet, we are going to see some practice questions.

(1) Find the slope of the line y = -3

(2) Find the slope of the line x = 5

(3) Find which of the following lines are horizontal lines and also write the equations of those lines.

(4) Check whether x = -2 is a horizontal or vertical line ?

(5) What is the equation of a line that passes through the point (3,-5) and has an undefined slope?

(6) What is the equation of the line that has slope=0 and passes through (-2,-5)?

(7) What is the slope of the line parallel to y = -8

## HOY and VUX worksheet - Solutions

Problem 1 :

Find the slope of the line y = -3

Solution :

Since the given line is in the form of y = a constant, it remembers the word (HOY). From this we come to know the given line is horizontal line.

Hence its slope is zero.

Problem 2 :

Find the slope of the line x = 5

Solution :

Since the given line is in the form of x = a constant, it remembers the word (VUX). From this we come to know that the given line is vertical line.

Hence its slope is undefined.

Problem 3 :

Find which of the following lines are horizontal lines and also write the equations of those lines.

Solution :

The lines which are parallel to x-axis is known as horizontal lines. Here the lines 1, 2,3 and 4 are parallel to x-axis.

Equation of line 1 :

y = 5

Equation of line 2 :

y = 2

Equation of line 3 :

y = -1

Equation of line 4 :

y = -2

Problem 4 :

Check whether x = -2 is a horizontal or vertical line ?

Solution :

Since the line x = -2 is perpendicular to the x-axis, it is vertical line.

Example 5 :

What is the equation of a line that passes through the point (3,-5) and has an undefined slope?

Solution :

Since the slope of the line passes which through the point (3, -5) is undefined, it should be vertical line.

This remembers the word "VUX".  So the equation is in the form x = a constant.

Hence equation of the required line is x = 3.

Example 6 :

What is the equation of the line that has slope=0 and passes through (-2,-5)?

Solution :

Since the slope of the required line is 0. It must be a horizontal line. So will be in the form of y = a constant.

Hence the equation of the required line is y = -5

Example 7 :

What is the slope of the line parallel to y = -8

Solution :

y = -8 is a vertical line. The line which is parallel to y = -8 is also a vertical line.

Hence its slope  =  undefined
