Answer:

5y - 2x = 8

Step-by-step explanation:

First off we have to find the y-intercept with : b = y-mx

[tex]b=2-(\frac{2}{5})(1)[/tex]

[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]

[tex]b=\frac{8}{5}[/tex]

now we have the point slope form

[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]

Multiply both sides by 5

[tex]5y=2x+8[/tex]

Subtract 2x from both sides

[tex]5y-2x=8[/tex]
