Answer:
The rate of change of a function with respect to a variable.
Step-by-step explanation:
For example: The slope of a constant value (like 3) is always 0. The slope of a line like 2x is 2, or 3x is 3 etc. and so on.
Answer:

Step-by-step explanation:
We have two fractions and are being asked to add them both.
5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.
50/100 + 8/100
58/100
This can be simplifed :


Given data:

Plot the points
on the number line.
Let us plot the first point
.
1 unit is completed. So count after 1 (indicated) in the number line.
point after 1 is 
point after
is 
point after
is 
point after
is
.
So, move 4 points after 1 in the number line is
.
Now plot the point
.
To make the denominator 9, multiply and divide numerator and denominator by 3.

2 unit is completed. So count after 2 (indicated) in the number line.
point after 2 is 
point after
is 
point after
is 
So, move 3 points after 2 in the number line is
.
The number line is attached below.
