Step-by-step explanation:
r-5r-6s+8s-15
-4r+2s-15
= 2s-4r-15
150, 155, 163, 168, 172, 177, 186, 190, 205
Slope formula m = (y2-y1) / (x2 - x1)
m = (1 - 6) / 7 - 1)
m = -5 / 6
Slope or parallel lines are the same
Slope = -5/6
Hello There!
The ratio is 1:3 therefore the answer is 1/3
Hope This Helps You!
Good Luck :)

Decreaseing means where it is going down
those blank points mean not including
brackets mean inlclude, it's like the ≤ or ≥ sign
parenthasees means not include, it's like the < or > sign
it is going down from -8 to -5, not including -5 so [-8,-5)
also going down from 4 to 8, not including 8, so [4,8)
the union is including both
[-8,-5) U [4,8) is answer for where the function is decreasing
