The graph of an estimated cost represented by cost equation, Y = a + bX, would be best described by which of the following descriptions:
A) A positive slope starting at the point of origin
B) A positive slope starting at the y-intercept
C) A horizontal line starting at the y-intercept
D) A negative slope starting at the y-intercept

Question

Quizplus · Accepted Answer

The cost equation Y = a + bX represents a linear equation where 'a' is the y-intercept and 'b' is the slope. Since 'b' represents the slope, if it is positive, the line will have a positive slope. The line does not start at the origin unless 'a' is zero; instead, it starts at the y-intercept 'a'.
