Step-by-step explanation:
Let the cost of the dress be "c"
ONE HALF the cost DECREASED by 12, can be written as:

Y = Mx + b
M = slope
Given that, the slope is 9/5
Answer:
m=3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Pull out like factors :
-4m + 12 = -4 • (m - 3)
Add 3 to both sides of the equation :
m = 3
