Answer:
-5y + 6 = -9
y = 3
Step-by-step explanation:
subtract 6 from both sides
-5y + 6 - 6 = -9 - 6
simplify
-5y = -15
divide both sides by -5
(-5y)/5 = (-15)/5
simplify
y = 3
Reflection that will produce an image with endpoints is y=-x
Answer:
The equation is 
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is

substitute
