i need help ASAP
f(3) = 4 f(0) =9
Y = mx + b
m = (9 -4) / (0 - 3) = -5/3
b = 9
Y = - 5/3 X + 9

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
