I’m really confused could someone me?

The answer to your question is: a and b are solutions,

96 crackers

Step-by-step explanation:

a) (4, 0)

                                    y = x - 4

                                    0 = 4 -4

                                    0 = 0                   It's a solution

b) (3, -1)

                                  y = x - 4

                                  -1 = 3 - 4

                                 -1 = -1                   It's a solution

c) (6, 3)

                                 y = x - 4

                                 3 = 6 - 4

                                3 = 2                    It's not a solution

d) (2, -4)

                               y = x - 4

                              -4 = 2 - 4

                              -4 = -2                 It's not a solution

Second question, 96 crackers

                       8 crackers  1 serving

                        x                12 serving

                      x = (12 x 8) / 1

                      x = 96 crackers

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
