Answer 1

$y = \frac{3}{5} x$

$x= - 10 \\ y = \frac{3}{5} \times ( - 10) = 3 \times ( - 2) = - 6$

$y = - 1.2 \\ \frac{3}{5} x = - 1.2 \\ x = - \frac{6}{5} \div \frac{3}{5} \\ x = - \frac{6 \times 5}{5 \times 3} \\ x = - 2$

$x = 0 \\ y = \frac{3}{5} \times 0 = 0$

$y = \frac{3}{5} \\ \frac{3}{5} x = \frac{3}{5} \\ x = \frac{3}{5} \div \frac{3}{5} \\ x = \frac{3 \times 5}{5 \times 3} \\ x = 1$

$x = 8.5 \\ y = \frac{3}{5} \times 8.5 = \frac{3 \times 17}{5 \times 2} = \frac{51}{10} = 5.1$

$y = 13.5 \\ \frac{3}{5} x = 13.5 \\ x = \frac{27}{2} \div \frac{3}{5} \\ x = \frac{27 \times 5}{2 \times 3} \\ x = \frac{9 \times 5}{2} \\ x = \frac{45}{2} \\ x = 22.5$
