Question

The constant is four

Answer 1

y = 4x

Explanation:

Take a pair of coordinates, like

(8,32) ; (4,16)

m = (Δy):(Δx)

= (32-16) : (8 - 4) = 4

y = mx + c

= 4x +c

Now substitute the values from one of the 2 coordinates' pair.

16 = 16 + c

c = 0

Therefore,

y = 4x

Answer 2

x=4

Explanation:

4x=16y

x=16divide4

x=4
