Lines B and C are perpendicular ⇒ answer C
Step-by-step explanation:
The product of the slopes of the perpendicular line is -1
The slopes of the parallel lines are equal
The slopes of two lines are and
1. If × = -1, then the two lines are perpendicular
2. If = , the the two lines are parallel
The equation of a line in slope-intercept form is y = m x + c, where m is
the slope of the line
Line A: y = x + 2
The slope of the line is =
Line B: y = x + 7
The slope of the line is =
Line C: y = 2 x + 4
The slope of the line is = 2
Line D: x +
The slope of the line is =
∵ =
∵ = 2
∵ × 2 = -1
∴ Line B and Line C are perpendicular because the product of their
slopes is -1
Lines B and C are perpendicular

Step-by-step explanation:
Answer:
7
Step-by-step explanation:
the median is the number in the middle of a sorted array
here it has 10 numbers, so the median will be the average of the 5th and the 6th number
the 5th number is 7 and the 6th number is 7
the average is (7+7)/2 = 7
so the median is 7
It’s -2 because of the turning that’s why it’s -2
When you multiply 5 by 1 you get 5. When you multiply 5 by 2 you get 10. If you keep doing this, you get a list of multiples of 5.
5
10
15
20
25
30
35
40
45
50
All of these numbers end in either 5 or 0. We can do the same with 2's and 10's.
2
4
6
8
10
12
14
16
18
20
For all 2's we can see that they are all even and end with an even number (0,2,4,6,8)
10
20
30
40
50
60
70
80
90
100
For 10's we can see that they all end in 0.
