20+40=60 and therefor 60 is less than 65
If the 2 lines are parallel, their slopes are the same.
The slope of both is
3+3
m = ---------- = 3
2 - 0
If the new line <span>passes through the point (−1, −1), then the equation in point slope form is:
y+1 = 3(x+1).</span>
Answer:
AB // CD and AD // BC, then ABCD is a parallelogram
Step-by-step explanation:
Step 2: Show AD // BC
A = (-3 , 3) and D = (0 , 0)
Find the slope of AD
![m_{AD}=\frac{0-3}{0--3}=\frac{-3}{3}=-1](https://tex.z-dn.net/?f=m_%7BAD%7D%3D%5Cfrac%7B0-3%7D%7B0--3%7D%3D%5Cfrac%7B-3%7D%7B3%7D%3D-1)
B = (2 , 5) and C = (5 , 2)
![m_{BC}=\frac{2-5}{5-2}=\frac{-3}{3}=-1](https://tex.z-dn.net/?f=m_%7BBC%7D%3D%5Cfrac%7B2-5%7D%7B5-2%7D%3D%5Cfrac%7B-3%7D%7B3%7D%3D-1)
The slope of AD = the slope of BC
So AD // BC because they have the same slope
Step 3:
Each two opposite sides are parallel in quadrilateral ABCD
So the quadrilateral is a parallelogram
1280, -2560, 5120
Multiply the preceding term by -2 and
