Example: Graphing the Linear Function f(x)=2x4f(x) = -2x - 4

To graph the linear function f(x)=2x4f(x) = -2x - 4, identify its key features from the slope-intercept form, f(x)=mx+bf(x) = mx + b. First, determine the slope, mm, and the yy-intercept, bb. For this function, the slope is m=2m = -2 and the yy-intercept is b=4b = -4. These values can then be used to graph the function by starting at the yy-intercept on the coordinate plane and using the slope to plot additional points.
