Write a linear function f with the values f (2) = 4 and f(-7) = 9. I think its -5/9+5 1/9 but im not sure, help?

f(x)=-5/9x+46/9

Step-by-step explanation:

Find the coordinates:(2,4)(-7,9)

Find the slope:

m=-5/9

Find the y-intercept:

b=46/9 (or 5 1/9)

Put it together:

You get f(x)=-5/9x+46/9

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
