Chapter 4.1, Problem 28MR

To determine

To represent: A relationship “Donald is 4 years older than Connie” using table, equation, and the graph.

Answer to Problem 28MR

The relationship between age of Connie and Donald is shown in Table-1, by the equation $y=x+4$ , and graphically in Figure-1.

Explanation of Solution

Given information:

Donald is 4 years older than Connie.

Methodused:

Establish the relationship between two variables.

Calculations:

Let the age of Connie be “ x ”.

Since Donald is 4 years older than Connie, therefore, age of Donald is $x+4$ years.

The table that shows age of Donald and Connie is given below.

Table-1

Name	Age ( in years)
Connie	x
Donald	x + 4

Let we denote age of Donald by dependent variable y .

The relationship between age of Donald and Connie is $y=x+4$ .

The equation that represents the relationship between age of Donald and Connie is $y=x+4$ .

The age relationship graph is the graph of equation $y=x+4$ shown in Figure-1 here.

  

The relationship between age of Donald and Connie is linear.

Conclusion:

The relationship between age of Connie and Donald is shown in Table-1, by the equation $y=x+4$ , and graphically in Figure-1.
