Graph ordered pairs of numbers on the coordinate plane and interprets information related to these sets of points. Graph a relation on the coordinate plane Distinguish between a relation and a function Graph a relation given an equation and domain Sketch a reasonable graph for a given relationship Interpret a graph in a real-world setting Use a computer or graphing calculator to explore the graphs of functions Compare ordered pairs to the line y = x and interpret the results Graph families of functions Determine if data are behaving in a linear fashion Find the solution set of open sentences in two variables when given replacement sets for the variables Graph a linear equation in two variables Graph a line given its slope and y-intercept Find the slope of a non-vertical line given the graph of a line or an equation of the line or two points on the line Describe the slope in a real-world linear relationship using real-world terms Write the slope-intercept form of an equation of a line Write the equation of a line which models a set of real data (line of best fit). Use the line that models real data to make prediction.
