Question

According to the graph what is the value of the constant in the equation below?

Answer 1

Constant = height/ width
Constant :
1/0.5=2
4/2=2
6/3=2 and so on.
Correct answer is C.2

Answer 2

The given graph is a straight line which is passing through the origin.Any line has a constant rate of increase or decrease.The constant of the equation can be calculated by using the gradient formula when two points are given.

For the points (2,4) and (3,6)

Gradient =
`(6-4)/(3-2) =(2)/(1) =2.`

Option c .2 is the right option.
