What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x + y - 1=0?

y=-2x+4

Step-by-step explanation:

2x+y-1=0

2x+y=0+1

2x+y=1

y=1-2x

y=-2x+1

y=mx+b where m=slope and b=y-intercept

parallel means same slope,

so the slope would still be -2.

y-y1=m(x-x1)

y-2=-2(x-1)

y=-2x+2+2

y=-2x+4
