Let’s Make a Holiday Tree The goal of this activity is to help students discover how to write the equation of a line with a restricted domain. They will then use that knowledge to draw a Holiday Tree in Desmos.
Name that Equation What is the equation of the horizontal blue line I'm pointing to.
Find the Bounds Drag the red lines to determine the xbounds of that same horizontal blue line I'm pointing to.
Syntax We will be drawing line segments in Desmos. The syntax for these line segments will be the equation of the line followed by its x-bounds in braces ({ }'s). So, for the horizontal blue line we’ve been talking about, our equation would be written: y=1 {-3<x<3}
Trace It Use the line tool to trace the green line I'm pointing to.
Name the y-intercept What is the y-intercept of the line you just drew (highlighted here)?
Name the slope What is the slope of the line you just drew (highlighted here)?
Name that Equation So. . . what is the equation of the highlighted line?
Drag your dot to how you are feeling: Keep going, I understand I’m a little confused Stop, I need help!
Find the Bounds Drag the red lines to determine the xbounds of the green line I'm pointing to.
Syntax: Your Turn Given what you've learned about the equation of the line, its x-bounds, and the Desmos syntax for graphing line segments, how would you write the equation of the green line being pointed to in this graph? Reminder: the equation of the horizontal blue line at the base of the tree is y=1 {-3<x<3}
Let’s Play! Now it’s your turn to build your very own holiday tree in Desmos.
In one minute, write the most important thing from today’s lesson.
