Lesson Description - Graphing Lines:
This lesson covers the idea of graphing lines. Students learn to graph a given linear equation using a chart. For example, to graph the equation y = x – 4, pick three values for x, such as –1, 0, and 1, and substitute these values into the equation to find the corresponding values of y. Next, plot the resulting points on a coordinate system and graph the line that passes through them. To graph the equation 3x + 5y = 5, first solve for y, to get y = -3/5x + 1. Then set up a chart, pick three values of x, such as –5, 0, and 5 (multiples of 5 so that the corresponding values of y will not be fractions), find the corresponding values of y, and graph the line.
