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 LaTeX: (1,1.5)( 1 , 1.5 ) is on the line. A line is graphed in a coordinate plane. The line begins at the origin. The line moves steadily upward and to the right passing through the point with coordinates 1 comma 1 point 5. Label the axes appropriately. Write an equation that represents the proportional relationship between oil and vinegar. Indicate the meaning of each variable. Explain the meaning of the point LaTeX: (1,1.5)( 1 , 1.5 ) in terms of the situation.
