Answer 2

@Sionainn

Answer 3

what are the points?

Answer 4

That would help wouldnt it? xD

(1, -5)

(1, 5)

(5, 1)

(-1, 5)

Answer 5

It would be (1,-5)

Answer 6

Can you help with another?

Answer 7

yea i agree its 1,-5 because if you plug 1 into the x for both of the equations, they value is greater than the y value

Answer 8

coordinate grid with plotted ordered pairs, point A at negative 5, 4 point B at 4, 7 point C at negative 2, 7 point D at negative 7, 1 point E at 4, negative 2 point F at 1, negative 6 point G at negative 3, negative 10 point H at negative 4, negative 4 point I at 9, 3 point J at 7, negative 4 and point K at 2, 3

The coordinate grid shows points A through K. Which points are solutions to the system of inequalities listed below?

2x + y ≤ 10

Answer 9

:)

Answer 10

just plug each of the coordinates into the equation and see if it is true or not.

Answer 11

B?

Answer 12

no. because if you use the coordinates for b which is (4,7) 2(4) + 7 is not less than or equal to ten

Answer 13

What is it then?

Answer 14

uhh thats alot of plugging and chugging haha. just pick a random one and try to see if that satisfies an equation.
