The two are perpendicular to each other because the two slopes are negative reciprocals
(Y2 - Y1) / (X2 - X1)
First slope:
( 1 - (-1)) / (-11 - (-6))
2/-5
Second slope:
(-13 - (-8)) / (-5 - (-3))
-5/-2 or 5/2
You know when two aliens are perpendicular when you multiply the two slopes and get -1 as the product
-2/5 X 5/2 = -1
Thus the two lines are perpendicular to each other.
Answer:
X-intercepts: (-5,0)
Y-Intercepts: (0,2)
Step-by-step explanation:
Answer:
17. (B)
18. both opposite sides are equal in length and height.
Step-by-step explanation:
.1= a tenth.
.01= a hundreth.
.001= a thousandth.
So,
Four tenths, two hundredths, and three thousandths.
I hope this helps!
