Answer:
Option A
Step-by-step explanation:
A linear function's standard form is represented by the equation
[tex]y=mx+b[/tex]
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
[tex]y=mx+b\\y=\frac{7}{2}x+9[/tex]
So option A is our answer
