Work shown below!

Step-by-step explanation:

Slope-intercept form: y = mx + b

11. $y=\frac{2}{5}x+1$

12. 3x - 7y = 28

Subtract 3x from both sides;

-7y = -3x + 28

Divide both sides by -7

$y = \frac{3}{7} x-4$

13. $y+4=\frac{1}{2}(x+1)$

Distribute;

$y+4=\frac{1}{2}x+\frac{1}{2}$

Subtract 4 from both sides;

$y=\frac{1}{2}x-\frac{7}{2}$
