Question

Determine 3 solutions to this equation: 4x-2y=8 using this t graph.

x|y
---
0|y
1|y
2|y

Answer 1

When x = 0,
4(0) - 2y = 8
-2y = 8
y = -4

When x = 1,
4(1) - 2y = 8
-2y = 8 - 4 = 4
y = -2

When x = 2,
4(2) - 2y = 8
-2y = 8 - 8 = 0
y = 0

The required solutions are (0, -4), (1, -2), (2, 0)
