In Linear Functions, we saw that that the graph of a linear function is a straight line. We were also able to see the points of the function as well as the initial value from a graph. By graphing two functions,
How do you graph linear functions? Example: To graph a function such asf(x) = y = 2x + 7, we can select a table of values, plot and connect the points. To fill the table, we choose values forxand use the function to get the values ofyas shown in the following table. x -3.5...
