Where is a graph positive?
Above the x-axis
A graph that is a non-vertical line is considered?
What is a linear Function?
Slope formula
What is the (y2-y1) / (x2-x1)
A relation where every input has exactly one output.
What is a function?
What is the range of the following relation? {(5,7),(-3,-2),(0,1),(5,4)}
What is {-2, 1, 4, 7}?
What is the name of the test to determine if a graph is a function or not?
What is vertical line test
Given a linear graph, to find slope, we use...
"change in y" over "change in x"
"rise" over "run."
A set of all the x-values.
What is domain?
Find the domain of the following function?
1 --> -5
-1 --> -7
-3 --> -9
What is [-3, -1, 1]?
If a graph has two arrows pointing up on the ends, how would you describe the end behavior?
As x goes to the left, y goes up. As x goes to the right, y goes up.
If you use the vertical line test and it intersects the graph at more than one place, is the graph a function?
What is No?
Identify the slope (m) and y-intercept (b):
10y = -5x + 30
m = -1/2
b = 3
The x-axis is labeled "number of people". Is the domain discrete or continuous?
