Answer:
Step-by-step explanation:
Plug the point (-1,20) into the equation.
20 = a|-1|+7
13 = a|-1|
13 = a ⋅ 1
a= 13
:::::
(1,20) is another point on the graph.
As i can see there is a table a bove so the x is the first number which going up the graph and the y is across the line
The value of x when y = 14 is 8.4

<h3>How to solve variation ?</h3>
y, varies directly as x. Therefore,
y ∝ x
Therefore,
y = kx
where
- k =constant of proportionality
Therefore,
10 = 6k
k = 10 / 6
k = 5 / 3
Hence, when y = 14
y = kx
14 = 5 / 3 x
cross multiply
42 = 5x
x = 42 / 5
x = 8.4
