Which two pairs of points lie on perpendicular lines?
1 answer:
Answer:
a and c
Step-by-step explanation:
Find the slope between each pair of points.
a. m = (16 − 10) / (6 − 3) = 2
b. m = (-3 − -12) / (-5 − -8) = 3
c. m = (3 − 4) / (2 − 0) = -1/2
Perpendicular lines have opposite inverse slopes. So a and c are perpendicular.

Answer:
y = 2
Step-by-step explanation:
Rearrange
2y = 7 - 3
2y = 4
make y on its own
y = 2
Answer:
11
Step-by-step explanation:
square of 44 + 77
1st step = go with the number that is inside the square
that will 44+77 = 121
now using the square root , you may think about which number multiple by himself give you 121
11×11 =121
so square root of 121 = 11
