Question

Fiona wrote the linear equation y = x – 5. When Henry wrote his equation, they discovered that his equation had all the same solutions as Fiona’s. Which equation could be Henry’s?

Answer 1

It could be:
y=-X+5
no ?

Answer 2

Fiona equation is y= x-5
So Henry's equation would be x= y+5 by adding 5 for both sides of the equation

To check, let's say x=2

Fiona equation y= 2-5= -3

Henry equation when x=2, 2= y+5 so, y= 2-5= -3
