A variable point p(x, y) traces a graph in a two-dimensional plane. (0, 3) is one position of P. If x increases by 1 unit, y increases by 4 units. The equation of the graph is

A.

-3 = y+4x+1

B.

4y = -3 + x

C.

yx = 34

D.

4x = y + 3

Correct answer is D

P(x, y), P(0, 3) If x increases by 1 unit and y by 4 units, then ratio of x : y = 1 : 4

x1 = y4

y = 4x

Hence the sign of the graph is y + 3 = 4x
