Answer:
Growth: 3
y-intercept: 5
Step-by-step explanation:
1. Find the equation in slope-intercept form:
-6x+2y=10
2y=6x+10
y=3x+5
2. Then we can easily identify the growth and y-intercept.
Growth: 3
y-intercept: 5
The Lagrangian is
with critical points where the partial derivatives vanish.
Substitute 
into the last equation and solve for 
:
Then we get two critical points,
We get an absolute maximum of 
at the second point, and an absolute minimum of 
at the first point.
The equation looks like this:
26=x*3.5+8.50
where x is the number of pen you bought.
We solve it like this:
first, we subtract 8.50 from both sides:
17.50 =3.5*x
now we divide both sides by 3.5:
5=x
so you purchased 5 pens.
