Terms Flashcards
X intercept
It crosses the Y intercept
Y -intercept
It crosses the X- intercept
Discrete
Can only take particular values
Continuous
May take on any value
Equation of a line
Y=mx+b
When you want the x-intercepts :
(X,0) set y=0 then solve for X
When you want the y-intercepts
(0,y) set x=0 then solve for y
To find the equation :
Y=ax+b
Put the table in the calculator
Slope
How steep a straight line is
Domain , X-Coordinate, Input
Independent
Range,Y-Coordinate, Output
Dependent
What is a dependent variable ?
The variable in a function which represents the output values or the second coordinate in the ordered pairs.
Independent Variable?
The variable in a function which represents the input values or the first coordinate in the ordered pairs
Function Notation ?
A notation which traditionally replaces the dependent variable in a function with f(x)
Solution
Is a value we can put in place of a variable (such as x) that makes the question true Ex: x-2=4
