Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (2, 0)

Point (0, 2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{2-0}{0-2}$
[Fraction] Subtract: $\displaystyle m=\frac{2}{-2}$
[Fraction] Divide: $\displaystyle m=-1$

Find the maximum value of c=6x+2y

scoundrel [369]

Answer:

∞

Step-by-step explanation:

c can have any value you like.

There is no maximum. We say it can approach infinity.

Additional comment

There may be some maximum imposed by constraints not shown here. Since we don't know what those constraints are, we cannot tell you what the maximum is.
