Graphing Relations Discrete Continuous Linear Positive

function whose values are distinct and separate and not connected; values are not continuous. Discrete functions are defined by their domain.

• discrete function

• linear function

• continuous function

• association

a relationship with a constant rate of change represented by a graph that forms a straight line

• Linear equation in two variables

• no linear correlation

• positive linear correlation

• negative linear correlation

trend of points to ascend from left to right

• negative linear correlation

• positive linear correlation

• linear correlation

• no linear correlation

line of best fit representing a set of bivariate data

• linear equation

• negative equation

• positive equation

• regression equation

the steepness of a line; rate of change in y (vertical) compared to change in x (horizontal),  or  or , denoted as m in y = mx + b

• x-intercept

• y-intercept

• slope of a line

• zeros

x coordinate of a point at which the relation crosses the x-axis, meaning the y coordinate equals zero, (x, 0)

• y-intercept

• x-intercept

• zeros

• slope of a line

y coordinate of a point at which the relation crosses the y-axis, meaning the x coordinate equals zero, (0, y)

• x-intercept

• y-intercept

• zeros

• slope of a line

the value(s) of x such that the y value of the relation equals zero
