X varies directly as y
x = ky
3 = 2k
k =
when x =9
9 =y
= y
∴y = 6

Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 5) ← 2 points on the line
m = =
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = x + 2 ← equation of line
