a system of equations or inequalities that has at least 1 solution. | consistent system |
a system of equations or inequalities that has infinitely many solutions. | dependent system |
a system of inequalities or equations that has no solution | inconsistent system |
a system of inequalities that has exactly 1 solution. | independent system |
a system of equations in which all of the equations are linear. | system of linear equations |
1. graphing- 2. substitution method 3. elimination method | 3 ways to solve linear equations |
an inequality that can be written as ax<b, ax>b, ax<_b, ax>_b | linear inequality |
a linear relationship between 2 variables, x&y, that can be written in the form y=kx. | direct variation |
a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. | rate of change |
a function that can be written in the form y=mx+b. | linear function |
a transformation that reflects a graph across a line called the line of reflection. | reflection |
a transformation that rotates or turns a figure about a point called the center of rotation | rotation |
a change in the position, size, or shape of a figure or graph. | transformation |
a transformation that shifts or slides every point of a figure or graph the same difference in the same direction. | translation |
the x-coordinates of the points where a graph intersects the x-axis. | X- intercept |
a list of numbers that often form a pattern. | sequence |
a sequence whose successive terms differ by the same non0 number d, called the common difference. | arithmetic sequence |
a graph made up of unconnected points. | discrete graph |
a relation in which every domain value is paired with exactly 1 range value. | function |
a graph with points plotted to show a possible relationship between 2 sets of data. | scatter plot |
2 data sets have this if 1 set of data values increases as the other set decreases. | negative correlation |
something used to determine whether a relation is a function. | vertical line test p. 247 |
