#1

  • x-4y≤-12
  • -4y≤-x-12
  • 4y≥x+12
  • y≥1/4x+3

Put (0,0)

  • 0≥0+3 is false

Shading will be away from origin.

y inetercept

  • y=3(when x=0)

Check the direction of line by taking 4 and -4

  • y=4/4+3=y=4
  • y=-4/4+3=-1+3=2

The graph should bend down on left side while rise up in right side

Option A

#2

  • 5x-4y>4
  • -4y>-5x+4
  • 4y<5x-4
  • y<5/4x-1

Putting origin in it

  • 0>-1

Shading away from origin

And

  • x+y<2
  • y<2-x

Putting origin

  • 0<2

Shading towards origin

  • Option B as shading should be downwards here

Answer:

BELOW

Explanation:

DO I HEAR 100 POINTS? Yes.

For the first image, that answer is A.

For the second image, I'm a bit confused on which problems you want me to do, so I'll do number 10, 11, and 14.

10) Yeah, you're correct, it is J.

11) (1,-6), (-2,-5), (8,2) (4,0) and I can't see the last point so..

14) Can't see the question :(
