Y=2x or y=x+2 If you plug in the ordered pairs for both, they fit.
-4x+y=1
Answer is:
y=4x-1
——————
-2x+y=1
Answer is:
y=2x+1
If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2
Fill in the point that it has to pass through on y and x
1=-1/2(0) + b
1=0+b
1=b
Then go back to the standard form y=mx + b and fill in the slope and y intercept
Y= -1/2x + 1
The graph represents f(x)=-2x-1
