Answer:
A = 20
Step-by-step explanation:
12/3 = A/5
60 = 3A
A = 60÷3 = 20
Answer:
your slope is 1
Step-by-step explanation:
You would use the formula y2-y1/x2-x1=m you would do -12-(-9)/-6-(-9)
which would give you 3/3 which simplifies to 1.
After a reflection across line y=x the vertices of triangle P’Q’R’ are as follows
P’= (-1,-7)
Q’= (-8-7)
R’= (-3,3)
Y=(1)/(3)x-9 that’s the answer
