Answer:
-25
Step-by-step explanation:
You must first pick two points. I picked the points of (4, 400) and (8, 300). You can pick different points and still get the right answer.
Subtract the y's and the x's. Divide the difference of y by the difference of x.
400 - 300 = 100
4 - 8 = -4
100/-4 = -25
The slope, or rate of change, is -25.

Answer:
₹996
Step-by-step explanation:
Area painted = area of wall - area of wall posture
Area of a rectangle = length x breadth
= 10.5m x 8.5m = 89.25m^2
Area of a square
length x length
2.5m x 2.5m = 6.25m^2
Area painted = 89.25m^2 - 6.25m^2 = 83m^2
Total cost of area painted = 83m^2 x 12 = 996
