Sagot :
Answer:
Parallel
Step-by-step explanation:
So the best way to compare two lines is to convert it into slope-intercept form which is given in the form of: y=mx+b where m is the slope, and b is the y-intercept, in this form it's really easy to see if they're the same line, parallel, or perpendicular.
Original Equation:
2x - y = -1
Subtract 2x from both sides
-y = -2x - 1
Divide both sides by -1
y = 2x + 1
Original Equation:
4x - 2y = 6
Subtract 4x from both sides
-2y = -4x + 6
Divide both sides by -2
y = 2x - 3
As you can see both equations have a slope of 2, but different y-intercepts, so they're not the same line, but they'll also never intersect, because they increase by the same amount, thus they are parallel
