A=2x+y²/7 make y the subject of the formula

y=√(7A-2x)

Step-by-step explanation:

A=2x+y²/7

Multiplying both sides by 7

7A=2x+y²

7A-2x=y²

Taking square root on both sides

y=√(7A-2x)

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.
