True or False-A relation is a set of ordered pairs
What is TRUE?
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)
The vertical axis on the graph is called the _____ axis.
Y axis
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
What is the solution to the system: y=4x+3 and y=2x-1
(-2, -5)
In a function, the x values are also called domain or ____put.
input
What is the slope of this line?
positive 2/1 or 2
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.
Does the following system have One, No Solutions, or Infinite Solutions?
2x+y = 5
y=5 -2x
Infinite solutions
The set of second coordinates in a relation or the y values can also be called the _______.
Output
Is this slope positive or negative? \
Negative
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.
x | y |
2 | 4 |
1 | 5 |
2 | 6 |
Does the solution have one, no solutions or infinite solutions?
y+8=5x
10x+16=2y
No solutions
A relation that assigns exactly one value in the input/range to each value in the output/domain?
What is a function?
What is the slope of this line?
negative 3/4, or -3/4
The point where a line crosses the y axis is called what?
y-intercept
What type of function is this?
Non-Linear because it would not make a straight line
Does this system have one, none, or infinite solutions?
3x-2y=5
x=4y-5
One solution
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.
In the equation y=4x + 6 what value is the slope of the line?
4
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.
How many solutions does the graph of the system of equations show?
infinite or many solutions
