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
