Lesson 27 of 95

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  more...

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.  less...
