Question

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?

Answer 1

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

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
