Question

In linear trend y=a +bc, if b is positive it indicates

Answer 1

Answer:

In the equation, yc=a+bx, of the trend, a represents the trend of the variable when x=0 and b represents the slope of the trend line. If b is positive, the trend line will be upward and if b is negative the trend line will be downward.

Answer 2

In linear trend y=a +bc, if b is positive it indicates a positive slope.

The given linear trend matches the equation of a straight line.

given trend: y = bc + a

equation of a straight line: y = mx + c

Here m represents the slope of the line. If m is positive that means the ratio of y to x is increasing, i.e. the line is moving in the upward direction.

Similarly, if we compare this to the linear equation provided to us we can see that in

y = bc + a

b represents the slope of the linear trend, c is the variable, while a will be the constant. So if the value of b is positive then the slope will be positive and the linear trend will increase in the upward direction.
