Linear Equations and Inequalities in 2-Variables
Question | Answer |
---|---|
intercepts | where the parabola crosses the x-axis; where a line crosses the x- and/or y-axis |
line of best fit | a line that most accurately represents a set of data and is used to determine whether there is a relationship or trend between paired data |
linear function | Data sets that have a constant rate of change and forms a line, have x as the input variable where x is raised only to the first power, and graphs that are straight lines |
linear inequality | an inequlaity that is the result of replacing the = sign in a linear equation with <, ≤, >, or ≥; when graphed the solutions are in the shaded part of the graph |
point-slope form | equations written as y-y1=m(x-x1) |
scatterplot | compares two sets of data to see relationships |
slope | "the steepness of a line and is defined as rise over run or (y2-y1)/(x2 - x1)" |
slope-intercept form | y = mx + b, where m= slope b = y intercept and (x , y) shows the coordinate of a point on the line |
standard form | ax + by = c where a, b and c are integers |
