Answer:
-1
Step-by-step explanation:
solution:
(-2 , -1) = (x1 , y1)
(-1 ,-2) = (x2 , y2)
we know that,
slope = (y2 - y1)/(x2 - x1)
=(-2 - -1)/ (-1 - -2)
=(-2 + 1) / (-1 + 2)
= -1/1
=-1
slope = -1
Answer:
That one
Step-by-step explanation:
It's kinda obvious if you look at the choices.
Answer:
x=135°
Step-by-step explanation:
45°- 180°=135x
{k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64}
{k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}
{(k - 4)(k + 6) = 0, (k - 7)(k + 9) = 0}
{k = -6, 4, -9, 7)
Therefore, range = {-9, -6, 4, 7)
