Question

if z is directly proportional to y and z = 48 when y = 6 ,
i ) find an equation connecting y and z ,
ii ) draw the graph of z against y .
​

Answer 1

Answer:

z is proportional y. So z = k.h where k is a constant. this eqn put z=48 and y=6, you will get the value of k =8. So the equati on = z=8y for graph first take z=8, put this value in eqation you get y = 1 so one point is (1,8). another point will be (0,0). put these two points in graph paper
