The phrase meaning the relationship between two changing quantities is the
Rate of change.
The ratio for the vertical change(or rise) to the horizontal change or (run) is called the
A relationship that can be represented by a function in the form y = kx is called a
An equation that models a linear function is called a
The slope-intercept form of a linear equation is given by
y = mx + b
The point-slope form of a linear equation is given by
y – y₁ = m(x - x₁)
The standard form of a linear equation is given by
Ax + By = C
The x- and y-coordinates where a graph crosses the x- and y-axis are called the
x- and y-intercepts
Lines in the same plane that do not intersect are called
Lines that intersect to form right angles are called
Two numbers whose product is -1 are called
The slopes of parallel lines are
The slopes of perpendicular lines are
A graph that relates two different sets of data by displaying them as ordered pairs is called a
A line on a scatter plot, drawn near the points, that shows a correlation is called a
Using a trend line to estimate a value between known values is called
Using a trend line to estimate values outside the range of known values is called
The trend line that shows the relationship between two sets of data the most accurately is called the
Line of best fit
Functions that have V- shaped graphs that open up or down are called
Absolute value functions
A shift of a graph horizontally, vertically, or both is also called a
