Answer:
5) y=-3x+1 6) y=1/2x-1
Step-by-step explanation:
5) y-y1=m(x-x1)
y-(-5)=-3(x-2)
y+5=-3(x-2)
y=-3x+6-5
y=-3x+1
------------------
6) y-y1=m(x-x1)
y-1=1/2(x-4)
y=1/2x-4/2+1
y=1/2x-2+1
y=1/2x-1
Answer:
180 miles
Step-by-step explanation:
if you divide 72 by 4 you can see what 1/10 of the trip is, which is 18. 18 times 10 (since 18 is one tenth of it) equals 180. hope this helps!
(m,n).....slope = n/m
slope of line perpendicular = -m/n
