x + y + z = ?
Slide 6 - Open question
Learning goals
I am able to draw the graph given a linear function.
I understand y = ax + b.
Slide 7 - Slide
Consider the fucntion y = x + 2
Find a point on the function's graph.
Slide 8 - Open question
I am able to draw the graph given a linear function.
Not yet
Just a little, for now
Getting there
I gots it
Slide 9 - Poll
Lines in Geogebra and y = ax + b
functions in the form y = ax + b are, for example:
y = 3x - 1, y = -10x + 3, y = 1/2x etc.
I will use Geogebra to show you how changing a and b affects a linear graph.
