Final answer:
The equation f(x) =1.99x + 3 represents a linear function. The slope is 1.99 and the y-intercept is 3. To graph the equation, choose different values for x, find the corresponding y-values, and connect the points.
Step-by-step explanation:
In the equation f(x) =1.99x + 3, 1.99 is the slope (m) and 3 is the y-intercept (b). The slope represents the rate of change of the function, while the y-intercept is the value of y when x is equal to 0. To graph the equation, you can plot points by choosing different values for x, substituting them into the equation to find the corresponding y-values, and then connecting the points.
