Question

Write an equation for a direct variation that includes the point (4, 16)

Answer 1

Answer:

therefore for direct variation that will include the point (4, 16) is  y = 4x

Step-by-step explanation:

i) for direct variation we can say that y = k $\times$ x

ii) substituting the given values of x and y into the equation in i) we get

16 = k $\times$ 4

Therefore  k  = $\frac{16}{4}$ = 4

iii) therefore for direct variation that will include the point (4, 16) is  y = 4x
