Answer: change in y over Change in x(slope)
2. 3/3 or 1
4. 5/4
6.4/5
8.1/4
10.-2/-3
12.1/-3
14.-9/9 or -1
1.
3x + 3 = 21
3x = 21-3
3x = 18
x = 18/3
Therefore,
x = 6
So option ( B) is the correct one.
2.

Therefore option (B) is the correct one here too.
The median of the data is 60. That means the two middle numbers divided by 2 = 60.
(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59
x + 2 = 59 + 2 = 61
so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93
Inverse works in this way:
y = 1/9x + 2,
you should swap the places of x and y and find y again, in this case it will be
x = 1/9y + 2 => x-2 = 1/9y => (x-2) * 9y = 1 => 9y = 1/(x-2)
and finally we got
y =
50 divided by 50= 1
1 plus 40= 41
41 minus 60= -19
So your final answer is -19.
Hope it helps.
