A recipe for salad dressing calls for 3 tablespoons of oil for every 2 tablespoons of vinegar. The line represents the relationship between the amount of oil and the amount of vinegar needed to make salad dressing according to this recipe. The point (1,1.5) is on the line.

Part a), Part b) and Part c) see the explanation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x > the amount of vinegar in tablespoons

y > the amount of oil in tablespoons

In this problem

The relationship between the variables x and y represent a proportional variation

The constant of proportionality k is equal to the ratio of the recipe

so

substitute

The linear equation is equal to

Explain the meaning of the point (1.1.5)

we have

x=1, y=1.5

In the context of the situation

This means >The amount of oil needed is 1 (tablespoon) if the amount of vinegar used is 1.5 (tablespoons) to make the salad dressing according to this recipe.
