### NCVPS Module 2

Another name for linear function, linear equation, line of best fit, goodness of line, least squares regression Linear Regression
The way most linear regressions are written - y = mx + b where m is the slope and b is the y-intercept Slope-intercept form
When the y increases as the x increases positive slope
When the y decreases as the x increases negative slope
This is when the y is 0. It's where the line crosses the x-axis x-intercept
This is the variable that we have some control over. It's graphed on the x-axis Independent Variable
This is the variable that is dependent on another variable. It's graphed on the y-axis Dependent Variable
This is when the x is 0 and considered the starting point. It's where the line crosses the y-axis. y-intercept
The rate of change, which is a ratio of the change in y's to the change in x's slope
Any relationship between two variables relation
A special type of relation where every value of the independent variable has one unique value of the dependent variable function
A way to indicate that an equation is a function - f(x) functional notation
A function whose graph is a single unbroken curve that you could draw without lifting your pencil from the paper continuous
A visual test for functions. If you place a vertical line anywhere along the graph of a function , it will only intersect the function once. Vertical Line Test
All the real number x-coordinates which can be used as the input of a function domain
All the real number y-coordinates which are determined for the outputs of a function range
