Answer :
y= -7x + 3
y + 7x = -7x + 7x + 3
y = 7x + 3
7x + 3 = -7x + 3
+7x +7x
14x + 3 = 3
-3 -3
14x = 0
14 14
x = 0
y = -7(0) + 3
y = 0 + 3
y = 3
(x, y) = (0, 3)
y + 7x = -7x + 7x + 3
y = 7x + 3
7x + 3 = -7x + 3
+7x +7x
14x + 3 = 3
-3 -3
14x = 0
14 14
x = 0
y = -7(0) + 3
y = 0 + 3
y = 3
(x, y) = (0, 3)
