Question

Write four solutions of 2x + y = 7 .​

Answer 1

2x + y = 7

X = 7 - y /2

1)put y = 0, X = 7 - 0/2

X = 7/2

coordinates (7/2,0)

2)put y = 1, X = 7-1/2

X = 6/2 = 3

coordinates (3,1)

3)put y = 2 ,X = 7-2/2

X = 5/2

coordinates (5/2,2)

4)put y = 3, X = 7-3/2

X = 4/2 = 2

coordinates (2,3)
