Answer:
1
Step-by-step explanation:
Choose two points on the line: (-5, 0) and (0, 5)
Let the first point
= (-5, 0)
Let the second point
= (0, 5)
Use the gradient formula:

----------------------------------------------------------------------------------------------------
If you want to find the equation of the line, use the point-gradient form of a linear equation: 
(where
is the gradient and
is a point on the line)
Substituting the values into the formula:



Therefore, the equation of the line is y = x + 5
Fraction on a number line is a visual mathematical representation of fractions. It is done by plotting the given fraction(s) on the number line where the section or the distance between two integers is divided into equal parts which are equal to the denominator of the given fraction.
