we need to find d=equation, so:
−8+6=−10+10
-8d=-10k+10-6
-8d=-10k+4
d=(-10k+4)/(-8)

So the answer is:
d=(5/4)k-1/2
or
d=1.25k-0.5
27 treats per 3 minutes = 9 : 1
if the ratio is 9:1, multiply by 8, and you get
72 treats per 8 minutes
you're welcome!
Answer:

Step-by-step explanation:
Slope-intercept form: y = mx + b
The line intersect Y-axis at y=0 so b = 0
The line passses through points (0, 0) and (2, -1), so the slope:

Therefore the equation:

Answer:
C. 3x + 8
Step-by-step explanation:
A. can be factored; Factor 5 from all terms:
(15x - 10)/5 = 3x - 2
B. can be factored; Factor 4 from all terms:
(4x + 8)/4 = x + 2
D. can be factored; Factor 2 from all terms:
(2x - 2)/2 = x - 1
