Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x
is 10/7. In other words, a change of 1 unit in x corresponds to a change of 10/7 units in y.
1 answer:
The graph of a proportional relationship passes through the origin, and as a constant slope
The given parameter is:
- Proportionality constant (k) = 10/7
For a proportional relationship, the equation of the graph is represented as:
Substitute 10/7 for k
See attachment for the graph of the proportional relationship

Answer:
Approximately 34 grams of the healthy food
Step-by-step explanation:
For know the minimum value to be eaten daily to provide the requirement of both vitamins, is necessary to calculate the minimum value for every vitamin, so:
- vitamin E: We are going to use the rule of three in which 1 gram have 7% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:
1 gram --------------7%
X grams -----------100%
So, it is necessary approximately 15 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.
- vitamin A: We are going to use the rule of three in which 1 gram have 3% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:
1 gram --------------3%
X grams -----------100%
So, it is necessary approximately 34 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.
Finally for satisfy with both minimum daily requirement, we need to eat at least 34 grams of healthy food, because it is the maximum between the two X values.
