Unit 3: Linear Graphing Flashcards
1
Q
Linear
A
Relationship between two variables that forms a straight line. No: Curves/ turns.
2
Q
Ordered Pair
A
Gives location of a point on the coordinate plane. They are called ordered pairs because the order matters.
3
Q
Proportional
A
When corresponding elements have a constant ratio.
4
Q
Rate Of Change
A
A ratio oh how fast a graph’s Y- variable changes compared to it’s X-variable. (AKA: Slope)
5
Q
Slope
A
Steepness of a line
Rise over run
Change in Y over change in X
(AKA: Rate of Change)
6
Q
Slope- Intercept Form
A
Equation of a straight line in the form of Y=mx+b where m is the slope and b is it’s Y-intercept.
7
Q
X- Axis
A
The line on a graph that runs horizontal.
8
Q
Y- Axis
A
the line on the graph that runs vertical.
9
Q
Y- intercept
A
The point where a line crosses the Y- Axis of a graph.
