i need help ASAP

f(3) = 4

f(0) = 9

first point is (3,4)

second point (0, 9)

now we figure out the slope using m = ( y_{2 }- y_{1})/(x_{2
}- x_{1})

so, m = (9 - 4)/(0 - 3) = -5/3

we use this formula to get equation of line:

y = mx + b

let's use point one:

4 = (-5/3)(3) + b

4 = -5 + b

so,

b = 9

therefore,

**y = (-5/3)x + 9**
