Answer 1

1-

$y = - 2.5x \\ - 10 = - 2.5x \\ - 2 .5x = - 10 \\ \times = - 10 \div - 2.5 \\ \times = 4$

2-

$y = 1 \frac{1}{2} x \\ y = \frac{3}{2} \times 4 \\ y = 1.5 \times 4 \\ y = 6$

3-

$y = 3.5 \\ - 3.5 = 3.5x \\ 3.5x = - 3.5 \\ x = 1$

4-

$y = - 3\frac{5}{10} x \\ y = - 3\frac{5}{10} \times 2 \\ y = - 3.5 \times 2 \\ y = - 7$
