Answer:
Work shown below!
Step-by-step explanation:
Slope-intercept form: y = mx + b
11. [tex]y=\frac{2}{5}x+1[/tex]
12. 3x - 7y = 28
Subtract 3x from both sides;
-7y = -3x + 28
Divide both sides by -7
[tex]y = \frac{3}{7} x-4[/tex]
13. [tex]y+4=\frac{1}{2}(x+1)[/tex]
Distribute;
[tex]y+4=\frac{1}{2}x+\frac{1}{2}[/tex]
Subtract 4 from both sides;
[tex]y=\frac{1}{2}x-\frac{7}{2}[/tex]
