Grade 8-12 
Mathematics 
(Algebra I) 
Standard 8

Students understand the concepts of parallel and
perpendicular lines and how their slopes are
related, and they are able to find the equation
of a line perpendicular to a given line that
passes through a given point.

Previously Published Data 

1.) Students will write an equation for a line parallel to: 

y = 3x + 14 

2x + y = 6 

Graph both equation on the same axes. 


2.) Students will write an equation for a line perpendicular to : 

5x - 2y = 10 

y = 3x - 4 

Graph both equations using the same axes. 


3.) Students will determine the slope of a line parallel to: 

8 = -4x + 2y 

-2x + 1/2y = 16 



Previously Published Data 

1.) Students will describe how to find an equation for a line perpendicular to y = 4x + 3. 


2.) Students will explain how to find a line parallel to the same equation above.
