A straight line is expressed by the equation, y = mx + c, where m is the slope of the line and c is the y-intercept, i.e. the y coordinate of the location where the line crosses the y-axis (see Figure 1).

A straight line is expressed by the equation, y = mx + c, where m is the slope of the line and c is the y-intercept, i.e. the y coordinate of the location where the line crosses the y-axis (see Figure 1).

A straight line is expressed by the equation, y = mx + c, where m is the slope of the line and c is the y-intercept, i.e. the y coordinate of the location where the line crosses the y-axis (see Figure 1). y = mx + c 4- slope m 3- 2 y-intercept C 1- 0 1 2 Figure 1 Define a class named Line to model a line. Use inline style to define the class. Use the provided template file, sbt.cpp to write your code. The requirements for the program are as follows: 1. Define a constructor that accepts two parameters to set the attributes m and c, respectively. Declare this constructor such that it can also serves as a default constructor (or default arguments constructor). In this case, it will model the line, y=x. 2. Define a function named read() that reads input from the keyboard to set the attributes m and c. 3. Define an overloaded operator that will be used for operations such as linel - line2 where linel and line2 are both Line objects. This operator returns another Line object with the slope equal to the slope of linel subtracted by the slope of line2; and the y-intercept equal to the y-intercept of line1 subtracted by the y-intercept of line2. For example, if linel represents the line equation y=5x+2 (i.e, m = 5 and c = 2), and line2 represents the line equation y=x+5 (i.e, m = 1 and c = 5) then 3 linel - line2 will result in a new line, y=4x-3 (i.e, m = 4 and c = -3). 3 4
