3.7 Graphing Flashcards
1
Q
Graph
A
A pictorial representation of the relationship between variables on a coordinate system
2
Q
Interpolation
A
The process of estimating values between measured values
-drawing a smooth curve that reasonably connects the known data points
3
Q
Extrapolation
A
The process of creating data points beyond the end of a line graph
- basic shape of curve used as guide
- always drawn with dotted line
4
Q
Use a bar graph when…
A
interpolation is unreasonable.
5
Q
Slope
A
The ratio of the change in one variable with respect to the other variable
-rise/run; change in vertical position/change in horizontal position; tangent
(y2 - y1)/(x2 - x1)
6
Q
Slope of Nonlinear Graph
A
Slope must be determined for each point by drawing a tangent line to the curve at the point in question
