How do I know when a slope declines or ascends?
babunello [35]

How to tell when a slope declines or ascends is to see if the line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the botto left and goes towards the top right.


Answer: If the line is a positive slope, y increases when x increases too. So the line on the graph starts at the bottom left and goes towards the top right ( than it's positive)

Write and solve an equation to find the number n.
garik1379 [7]
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3
