Answer:

Step-by-step explanation:
Here, the given expression is:

Now,as we know:

Now, 
Applying this to the given expression, we get:
where: b = 2, and k = 4
Hence, 
Answer:
63.21%
Step-by-step explanation:
First find the slope
(0+2)/(1-2) = 2/-1 = -2
Y = mx + b
Y = -2x + b
Plot in any point
-2 = -2(2) + b, b = 2
Solution: y = -2x + 2
Answer: The slope is -3/2
Step-by-step explanation:
To find the slope, find the difference in the y coordinates and divide it by the difference in the x coordinates.
y coordinates; 9 - 15 = -6
x coordinates : 8 - 4 = 4
Slope: -6/4 = -3/2
The possible answers might be 3 (or) -25. There’s no -25 among answers so I suppose it’s B.
