Identify an equation in point-slope form for the line perpindicular to y=-1/2x+11 that passes through (4, -8)

a.) y+8=2(x-4)
b.) y-8=1/2(x+4)
c.) y+8=1/2(x+4)
d.) y-4=2(x+8)

y=4/2x+6

Step-by-step explanation:

I used Desmos to get my answer. I used a peice of paper to line up with the point and the original line.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
