Which equation has a graph that is parallel to the graph of 2x − y = −1? A.2x + y = 8
B. y = −1/2x + 3
C. y − 1 = 2(x − 3)
D. y = −2x − 1

B

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2
