Answer:
the answer is A. that's my final ans
It would take approximately 12.5 hours
When we want to determine the relative position of two lines, the first thing we can do is to write them in the same form.
We can use the form y=mx+k, where m is the slope.
the given lines are lines in plane. The "skew" case cannot be considered.
i) if 2 lines have same slope, but different k, then they are parallel,
ii) if 2 lines have equal slope (m) and k, then they are coinciding
iii) if the multiplication of their slopes is -1, then they are perpendicular
iv) if the slopes are not equal, and their multiplication is not -1, then the lines are intersecting
2.
4x+2y=8
2y=-4x+8, divide by 2
y=-2x+4
the other line is y=2x+4
-2 and 2 are not the same so the lines are neither parallel, nor intersecting.
-2 * 2 is not equal to -1, so the lines are neither perpendicular.
The lines are intersecting.
