how do you graph coordinated points?
1 Understand the axes of the coordinate plane. 2 Understand the quadrants on the coordinate plane. 3 Learn how to graph points if you're working with an equation.

what is the definition of independent variable?
a variable (often denoted by x ) whose variation does not depend on that of another.

wich is a coordinate point. A) y= 1/2x + 2 B) M= 7m + 34
A

which is the letter that represents the independent variable and also the letter that represents the dependent variable?
dependent = Y independent = X
400
Function notation rules
function notation rules first you substitute the number for X and then, solve the function as normal
400
what is the domain and range of a relation?
range: is the set of the second numbers in each pair, or the y-values domain: is the set of all the first numbers of the ordered pairs . In other words, the domain is all of the x-values.

What's the name of the graph that dose not have a numerical value
Qualitive

wich is the dependent and independent variable in this example Y = 3x - 2
dependent = 3x independent = -2

What is the difference between function notation and function table.
There is no difference between them because a function table is made up of a function notation.
500
what makes a relation a function?
At first glance, a function looks just like a relation. It's a set of ordered pairs such as { (0,1) , (5, 22), (11,9) } Like a relation, a function has a domain and range made up of the x and y values of ordered pairs.
