True or False-A relation is a set of ordered pairs
What is TRUE?
100
How would your write the slope of a line that goes down 5 and to the right 2 between each point?
-5/2 (-5 numerator, 2 denominator)
100
The vertical axis on the graph is called the _____ axis.
Y axis
100
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
100
What is the solution to the system: y=4x+3 and y=2x-1
(-2, -5)
200
In a function, the x values are also called domain or ____put.
input
200
What is the slope of this line?
positive 2/1 or 2
200
How do you graph the point (-3,4)?
What is you go left 3 units on the x-axis then go up 4 units on the y-axis?
200
How can you tell if a graph of a function is LINEAR or NONLINEAR?
The graph of a linear function makes a straight line in a direction.
A nonlinear function would not be a straight line.
200
Does the following system have One, No Solutions, or Infinite Solutions?
2x+y = 5
y=5 -2x
Infinite solutions
300
The set of second coordinates in a relation or the y values can also be called the _______.
Output
300
Is this slope positive or negative? \
Negative
300
Give directions on how to graph the point (5, -2) on a graph.
to the right from (0,0) positive 5, then from there go down 2.
300
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
300
Does the solution have one, no solutions or infinite solutions?
y+8=5x
10x+16=2y
No solutions
400
A relation that assigns exactly one value in the input/range to each value in the output/domain?
What is a function?
400
What is the slope of this line?
negative 3/4, or -3/4
400
The point where a line crosses the y axis is called what?
y-intercept
400
What type of function is this?
Non-Linear because it would not make a straight line
400
Does this system have one, none, or infinite solutions?
3x-2y=5
x=4y-5
One solution
500
What is the Vertical Line Test?
The test to tell if a graph is a function. you use a vertical edge/line to see if the graph drawn hits more than one x value.
500
In the equation y=4x + 6 what value is the slope of the line?
4
500
How is slope calculated on a graph?
rise over run or "how much the line goes up and over", or any other general description of slope.
500
Is it a function?
What is NO because it does not pass the Vertical Line Test?
500
How many solutions does the graph of the system of equations show?
infinite or many solutions
