The equation is:

y= -2x + 3

Step-by-step explanation:

There are two ways to solve this:

You could do very long algebra but you could  also just plug in your information and make life easy for yourself.

Start of by plugging in your slope into the equation. (due to y=mx+b, m= slope=-2)

y= -2x + _

Then plug in the co-ordinates give.

(1) = -2(1) + z

Then solve for z

1 = -2 +z

+2  +2

z= 3

Then plug all your information in to get

y= -2x +3
