Final answer:
The linear function represented by the graph has a slope of 3 and a y-intercept of 9. The equation of the linear function is y = 3x + 9.
Step-by-step explanation:
The linear function represented by the graph has a slope of 3 and a y-intercept of 9. The slope of a line represents the rate of change of the y-values with respect to the x-values, while the y-intercept is the value of y when x=0. In this case, for every increase of 1 on the horizontal axis, the vertical axis increases by 3 units. The equation of the linear function is y = 3x + 9.
