Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
= k , that is
k = 
y =
xz ← equation of variation
When x = 2 and z = 3 , then
y =
× 2 × 3 = 5 × 2 = 10
The answers are 1/3, 2/6, 3/9, 4/12
Your first point is your y-intercept, which is -2. That means you plot a point at (0,-2).
From that point rise 3 and run (to the right) 4. Plot your second point there.
Connect the two points.
