Solutions
g(x) = [tex] \frac{1}{3} [/tex] - [tex] \frac{4}{3} [/tex] x
g(x) = - [tex] \frac{4}{3} [/tex] x + [tex] \frac{1}{3} [/tex]
x = -5
= g(x) = - [tex] \frac{4}{3} [/tex] × (-5) + [tex] \frac{1}{3} [/tex]
= [tex] \frac{20}{3} [/tex] + [tex] \frac{1}{3} [/tex]
= [tex] \frac{21}{3} [/tex]
= 7
(-5,7)

x = 7
= g(x) = - [tex] \frac{4}{3} [/tex] × (7) + [tex] \frac{1}{3} [/tex]
= [tex] \frac{-28}{3} [/tex] + [tex] \frac{1}{3} [/tex]
= [tex] \frac{-27}{3} [/tex] = -9
(-7,9)
x = (-7,9) y = (-5,7)
