Answer 1

$y = -2 x + 3$

$x = - 6 \\ y = - 2 \times ( - 6) + 3 = 12 + 3 = 15$

$x = - 3 \\ y = - 2 \times ( - 3) + 3 = 6 + 3 = 9$

$x = 0 \\ y = - 2 \times 0 + 3 = 3$

$x = 4 \\ y = - 2 \times 4 + 3 = - 8 + 3 = - 5$

$y = - 5 \\ - 2x + 3 = - 5 \\ - 2x = - 8 \\ 2x = 8 \\ x = 8 \div 2 \\ x = 4$

$y = - 10 \\ - 2x + 3 = - 10 \\ - 2x = - 10 - 3 \\ - 2x = - 13 \\ 2x = 13 \\ x = 13 \div 2 \\ x = 6.5$

$y = 3 \\ - 2x + 3 = 3 \\ - 2x = 3 - 3 \\ - 2x = 0 \\ x = 0$

$y = 13 \\ - 2x + 3 = 13 \\ - 2x = 13 - 3 \\ - 2x = 10 \\ x = 10 \div ( - 2) \\ x = - 5$
