Answer:

f(x) = [tex]-\frac{1}{4}[/tex] x - 2

Step-by-step explanation:

Slope of the line: m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

f(x) = mx + b (b - is y-intercept)

(0, - 2) Coordinates of y-intercept

(4, - 3)

m = [tex]\frac{-3+2}{4-0}[/tex] = [tex]-\frac{1}{4}[/tex]

f(x) = [tex]-\frac{1}{4}[/tex] x - 2
