Question

the vertical asymptote x = 30 means the concentration will always be less than 30%. the vertical asymptote x = 10 means the volume will always be greater than 10 milliliters. the y - intercept means the concentration will remain 30% if no solution is added. the y - intercept means the concentration will always be less than 30%.

Explanation:

Step1: Understand y - intercept concept

The y - intercept is the value of y when x = 0. In the context of the graph where x is the mL of 10% solution added and y is the percentage of saline, when x = 0 (no solution added), the value of y represents the initial concentration.

Step2: Analyze y - intercept value

From the graph, when x = 0, y = 30. This means that the initial concentration of the saline is 30%, i.e., the concentration will remain 30% if no solution is added.

Answer:

The y - intercept means the concentration will remain 30% if no solution is added.
