Question

If x is directly proportion to y and x1=5,y1=210 and x2 = 2, then find y2?

Answer 1

Answer:

y₂ = 84

Given that ;

• x is directly proportional to y

x 1 = 5

y 1 = 210

5 is directly proportional to 210

210 / 5

= 42

x₂ = 2

y₂ = ?

2 is directly proportional y₂

y₂ / 2

y₂ = 42 × 2

= 84

84 / 2

= 42

Hence ;

x is proportional to y
