Learning goals 

At the end of this lesson I can:

•  Give the equation for horizontal and vertical lines 
• Identify parallel, perpendicular and intersecting lines 

Equations of horizontal/vertical lines 

1. Find the coordinates of A, B, C and D

2. What do ALL the points on this line have in common? 

Equations of horizontal/vertical lines 

1. Find the coordinates of A, B, C and D

A(-1,3) B(1,3) C(4,3)  D(5,3)

2. What do ALL the points on this line have in common? 

They all have y-coordinate 3

Equations of horizontal/vertical lines 

For a Horizontal line, 

the y-coordinates will be the same for all points on the line. 

The equation of this line: y = 3 

Hint: look at where the line intersects the y-axis

Equations of horizontal/vertical lines 

How can you find the equation of a Vertical line? 

Hint: Look at where the line intersects the x-axis

What to do

- I really want a challenge                                                  Open the Pink slides on LessonUP

- I understand it, but I think a                                           Open the Blue slides on LessonUp

 bit more practice will help me                 

- I think more practice will help me,                                  Open the green slides on LessonUP

and would like to do more board work

What have you learned... 

1. Give the equation for the following line

What have you learned... 

A transversal is a line which intersects 2 other lines in different points

Which lines are transversals?
