Answer:
2x-y = -4
Step-by-step explanation:
We can use the point slope form of a line to write the equation and then convert it to standard form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y-2 =2(x--1)
y-2 =2(x+1)
y-2 =2x+2
The standard form is Ax +By =C
Subtract 2x from each side
-2x +y -2 =2x-2x+2
-2x+y-2 =2
Add 2 to each side
-2x+y -2+2 =2+2
-2x+y=4
The x term should be positive
Multiply by -1
2x-y = -4
