Answer:
slope of AB = Y2 -Y1/X2 -X1
=7 - 3/-5-(-5)
=4/-5 +5 = 4/0
= undefined ( a number divided by 0 is undefined)
slope of CD =9 -9/-10-1
= 0/-11
= 0
since AB is not equal to CD
THE LINES ARE PERPENDICULAR
Answer:
17 hours
Step-by-step explanation:
givens:
-he made $253 for 11 hours of work
-how many hours of work for $391

253h=391 times 11
253h=4301
divide 253 in both sides
4301/253
17 hours!
