Please help me with this as soon as possible

Hi the answer to this is super easy what you have to do is to substitute x with the number given by the chart and you will get y
So if we want to do the first one it will be

Y = 4 x (1) - 3
Y = 4 - 3
Y = 1

For the second one we got x = 6
So we do the same thing but with 6 and say
Y = 4 x (6) - 3
Y = 21

It seems confusing at first but I’m sure you’ll get the hang of it

Iagree that is the answer to the question
