Linear Equations and Inequalities in 2-Variables

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)
slope "the steepness of a line and is defined as rise over run or (y1-y2)/(x1 - x2)"
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"
