Answer:
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Step-by-step explanation:
First we know that a perpendicular line is one that intersects at a 90-degree angle. This is simply the negative inverse of the slope in our case. So, 4 turns into -1/4 and that is our new slope. Next we know that we want it to pass through the point (6,1). Right now our equation is y = -1/4x + b. We can plug (6,1) into this equation and solve.
1 = -1/4(6) + b
1 = -6/4 + b
4/4 + 6/4 = 10/4
10/4 = b
simplify: 5/2 or 2.5 = b
Now we have our y-intercept, so we can complete our equation.
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Fewer because October clearly is higher then where December will be when the time comes.
D, hope this helps because 1/2 is less than 1. and 5*1/2 is 2.5 and that is less than 5

X < 12 its actually very simple , just see that the x is on one side and nothing can be moved
