Question

Explain, in complete sentences, how you would use the graphing method to solve the following system of inequalities and what the final solution will look like on the coordinate plane.

x - 2y >= -8
7x + y < -6

>= means greater than or equal to, if you don't know :]

Answer 1

i love graphing! :D

Answer 2

I would solve so y is isolated

Answer 3

-2y>=-x-8
y<= x/2 +4

Answer 4

Alright :] Is the graphing method just the substitution method and then graphing it or ? .. I've never heard of the "graphing method."

Answer 5

y<= x/2 +4
y<-7x-6

you look at where it is shaded
