To find the slope (or gradient) of two points use the equation
(y2 - y1)/(x2 - x1)
where point 1 is (x1, y1) and point 2 is (x2, y2)
substitute the numbers in
(2 - 3)/(4 - 7)
which gives
-1/-3 = 1/3
Answer:
It is because they are fractions of the same numbers so if you devide the numerator, you will get the quotient
sorry for my spelling lol

Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
