if q is directly proportional ti p and q = 28 when p = 4 express q in terms of p

Materi: Proportionality

q = 28 when p = 4, this means there is a constant factor which relating the value of p and q. Find it first by dividing q to p,
28:4 = 7. Now, we can express q by p that,
q = 7p. q is shown as directly proportional to p
