The graph of f(1/2x) is a horizontal expansion of the graph of f(x) by a factor of 2. The mapping rule is (x, y) -> (2x, y)
(-4,2) -> (-8,2)
(-2,-2) -> (-4,-2)
(0,0) -> (0,0)
Plot those points to get the graph of f(1/2x).
-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5
