An equation written in = + form provides information about the graph. If the equation is y x b y = 1, then the slope, of the line is 1 or and the point where the line crosses the can x m, y-axis – be located at (0, -1). We also know, slope = = = m So we can plot some other points on the graph using this relationship between and values. y x A table of values can be used to determine the graph of a line. The is located on the y-intercept which is where the is 0. The change in each compared to the y-axis x-coordinate y-value corresponding can be verified by the patterns in the table of values. x-value
An equation written in y = x + b form provides information about the graph. If the equation is y = x – 1, then the slope, m, of the line is 1 or and the point where the line crosses the y-axis can be located at (0, -1). We also know, slope = m = = So we can plot some other points on the graph using this relationship between y and x values. A table of values can be used to determine the graph of a line. The y-intercept is located on the y-axis which is where the x-coordinate is 0. The change in each y-value compared to the corresponding x-value can be verified by the patterns in the table of values.
