1. ratio = 2 c of dressing / 4 lb of vegetables
Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.
Then d / v = 2/4 = 1/2 => d = v/2
Now you can make a table
v d
2 1
4 2
6 3
8 2
And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2
b) I already did it above as part ot the explanation: d/v = 1/2

(a) The model for the ratio of dressing and vegetables is the given by the equation
[tex]\rm\bold{ V = 2D}[/tex]
A catering company’s recipe for salad uses a ratio of 2 c of dressing 4 lb of vegetables.
(a) We have to draw a model for the ratio.
(b) We have to write the ratio of dressing to vegetables as a reduced fraction.
Dressing = 2c
Vegetables = 4lb
The ratio of both is formulated as 2c : 4lb
(a) Let us consider dressing is represented by D and amount of vegetables is represented by V then we can say that
[tex]\rm \dfrac{D}{V} = \dfrac{2}{4} = \dfrac{1}{2}[/tex]
hence when D increases by 1 unit variable V increases by two units and hence we can write
[tex]\rm V = 2D.....(1)[/tex]
The V and D values are shown in the table below
V D
1 2
2 4
3 6
Equation (1) represents the model for the given situation.
(b) The ratio of dressing to vegetables as a reduced fraction is given by
[tex]\rm \dfrac{D}{V} = \dfrac{1}{2}[/tex]
