Express each linear equation in the form $y = m x + b .$ Choose your answer.

1.	$x - y = 1$

y = x - 1

y = x + 1

y = - x + 1

None of the choices

Answer: $y = x - 1$

2.	$3 x + 2 y = 5$

y = \frac{3}{2} x + \frac{5}{2}

y = - \frac{3}{2} x + \frac{5}{2}

y = - \frac{3}{2} x - \frac{5}{2}

None of the choices

Answer: $y = - \frac{3}{2} x + \frac{5}{2}$

3.	$5 x - 3 y = 2$

y = \frac{5}{3} x - \frac{2}{3}

y = \frac{3}{5} x - \frac{3}{2}

y = - \frac{5}{3} x + \frac{2}{3}

None of the choices

Answer: $y = \frac{5}{3} x - \frac{2}{3}$

4.	$x + y = - 7$

y = x - 7

y = x + 7

y = - x - 7

None of the choices

Answer: $y = - x - 7$

5.	$2 x - y = 10$

y = 2 x - 10

y = 2 x + 10

y = - 2 x + 10

None of the choices

Answer: $y = 2 x - 10$

6.	$8 x - 4 y = 2$

y = - 2 x + \frac{1}{2}

y = 2 x - \frac{1}{2}

y = - 2 x - \frac{1}{2}

None of the choices

Answer: $y = 2 x - \frac{1}{2}$
