1) 5x - y = 5
y = 5x - 5
let x = 1, y = 0, coordinates (1, 0)
let x = 2, y = 5, coordinates (2, 5)
let x = 3, y = 10, coordinates (3, 10)
2) 3x - y = 3
y = 3x - 3
let x = 1, y = 0, coordinates (1, 0)
let x = 2, y = 3, coordinates (2, 3)
let x = 3, y = 6, coordinates (3, 6)
plot these points on graph page and get the answer.
