Answer:
Option A
Explanation:
A linear function's standard form is represented by the equation
![y=mx+b](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yj5waqmoy4i54laybzhhshd88hyo5w5rj5.png)
where m is the slope and b is the y-intercept(where the line crosses the y-axis).
So if a function has a slope of 7/2 which is the value of m and crosses the y-axis at 9 which is the value of b then the equation would be
![y=mx+b\\y=(7)/(2)x+9](https://img.qammunity.org/2021/formulas/mathematics/high-school/k9kokzraep78w5orlgak0ymoxje89harr2.png)
So option A is our answer
