Question

The equations 2x+y=5 and y=2x-4 are
Parallel
Perpendicular
Neither

Answer 1

Neither.

Explanation:

y=-2x+5

y=2x-4

slopes are -2,2

product of roots=-2×2=-4≠-1

neither the slopes are equal.

nor product of slopes =-1

so they are neither parallel nor perpendicular.

Answer 2

the answer is 100% neither
