Concept explainers
a.
The independent and dependent variables.
a.
Answer to Problem 1PT
Explanation of Solution
Given:
The equation to convert Celsius temperature C to Kelvin temperature K is shown in below figure:
Concept Used:
The intercepts of a line are the points where it intersects the horizontal and vertical axis. x -intercept if the point where the line intersect the x -axis and y -intercept is the point where the line intersects the y -axis.
Calculation:
In the given relation
So, Celsius temperature is the independent variable and the Kelvin temperature is the dependent variable.
Thus, C is the independent variable and K is the dependent variable.
b.
The C - and K -intercepts.

Answer to Problem 1PT
Explanation of Solution
Given:
The equation to convert Celsius temperature C to Kelvin temperature K is shown in below figure:
Concept Used:
The intercepts of a line are the points where it intersects the horizontal and vertical axis. x -intercept if the point where the line intersect the x -axis and y -intercept is the point where the line intersects the y -axis.
Calculation:
From the given graph is clear that the line intersects the horizontal line ( C -axis) at the point
Also, from the graph it is clear that the line intersects the vertical axis ( K -axis) at the point
Thus, C -intercept is
