Transcript Start

Audio Description: Part eleven; solving equations using graphing; example five.

TEACHER: Go down to... fourteen. 

BRANDON: Fourteen. X equals 5. 

TEACHER: Right. How do we do that? 

BRANDON: So that means we have 5 as the X coordinate. So that means we go on the X axis... starting from the origin, always we go to the right 5, 

BRANDON: and plot a point. 

TEACHER: Good. 

TEACHER: And how do you draw your line? 

BRANDON: It's a horizontal line.... 

TEACHER: Is it? 

BRANDON: No, wait. It's a vertical line. 

TEACHER: Okay. 

TEACHER: So do you want the Wikki Stix with the one end at the point? Or do you want it kinda in the middle, the point in the middle? 

BRANDON: I think we want it... 

TEACHER: No. 

TEACHER: In the middle. 

BRANDON: Yeah, okay. 

BRANDON: I was kind of questioning that, too. 

TEACHER: Just makes it easier. Then you can spread it out. Alright, how do you line it up? 

Audio Description: Brandon stretches the Wikki Stix vertically.

TEACHER: You shouldn't need a pencil or anything. This should be really, really easy... to graph. Let's see. 

BRANDON: Pretty good. 

TEACHER: Alright, how did you do that? 

BRANDON: l... uh... l... moved it until it was straight. 

TEACHER: You laid it across the raised line that was already there. Use your guidelines. That's why you have them. 

BRANDON: Yeah. 

TEACHER: Good job.
