Answer 1

Work shown below!

Explanation:

Slope-intercept form: y = mx + b

11.
`y=(2)/(5)x+1`

12. 3x - 7y = 28

Subtract 3x from both sides;

-7y = -3x + 28

Divide both sides by -7

`y = (3)/(7) x-4`

13.
`y+4=(1)/(2)(x+1)`

Distribute;

`y+4=(1)/(2)x+(1)/(2)`

Subtract 4 from both sides;

`y=(1)/(2)x-(7)/(2)`
