1
Function
Each input has one output
2
Relation
a set of ordered pairs
3
Linear
graph of the equation makes a straight line
4
Nonlinear
graph of the equation does NOT make a straight line
5
y-intercept
where the graph crosses the y-axis
6
slope
steepness of the line
7
slope of a graph
found using rise/run
8
proportional
two equal ratios
9
proportional on a graph
must be a straight line and cross through the origin (0,0)
10
Slope-Intercept Form
y = mx + b
11
Vertical Line Test
The test that is performed to check to see if a graph is a function.
12
Constant of Proportionality
"k" value in y = kx
13
Finding the Constant of Proportionality
Use y/x
14
Standard Form
ax + by = c
15
Rate of Change
the same as slope, Unit Rate, "m"
16
Slope of 2 Points
(y-y)/(x-x)
