Question

I already finished it but how do you know if it’s decreasing or increasing?

Please explain to me :)

Answer 1

the slope of the line will tell you whether it is decreasing or increasing.
negative slopes means it’s decreasing while positive slopes means the line is increasing.

Answer 2

If the slope is positive it is increasing if the slope is negative it is decreasing :)

Example:

Y=mX+b

If m is positive it is a positive slope
