Question

Which equation represents a line which is perpendicular to the line x – 2y = 2?

Answer 1

Answer:

Step-by-step explanation:

x-2y=2

2y=x-2

y=(x-2)/2

so the slope is 1/2

for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition

(1/2)m=-1

m=-2

the only line with a slope of -2 is

y=-2x+5
