Answer:

The equation is

[tex]y = - 2x + 6[/tex]

Step-by-step explanation:

First we find the measure

[tex]m = \frac{4 - 2}{1 - 2} = - 2[/tex]

Then the equation is

[tex]y = - 2x + c[/tex]

To find C we can usw any point

Then

[tex]2 = - 2 \times 2 + c \\ c = 6[/tex]

Then the equation is

[tex]y = - 2x + 6[/tex]
