Step-by-step explanation:
Solution:
x + 2y = 5
Put the value of x = 0 in the equation x + 2y = 5
0 + 2y = 5
2y = 5
2y/2 = 5/2
y = 5/2
(0, 5/2)
Put the value of y = 0,
x + 2 × 0 = 5
x = 5
(5, 0)
Put the value of x = 2,
2 + 2y = 5
2 – 2 + 2y = 5 - 2
2y = 3
2y/2 = 3/2
y = 3/2
(2, 3/2)
Put the value of y = 2,
x + 2 × 2 = 5
x + 4 = 5
x + 4 – 4 = 5 – 4
x = 1
(1, 2)
