If y varies directly with x and y = 26 when x = 8, write the equation that represents this direct variation relationship,

Step-by-step explanation:

General equation for directly proportional variables: y = kx, where k is a real constant

When x = 8, y = 26.

Hence y = 26/8 x or y = 13/4 x.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
