Question

If y =4 when x=10,find y when x=5

Answer 1

Answer:

Y = 2 when x=5

Step-by-step explanation:

Look at the rate of change from the different x's. It's two because we do 10/5. So because we halved the x, we half the y. Therefore we do 4/2, giving us 2.

Answer 2

If y is 4 and x is 10, y is 2 and x is 5
