Question

Please help me, I can't get this question, its for 5th graders, please

Answer 1

The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc

The rule will say x + y = 23

Answer 2

Answer:

y = -16x + 23

Step-by-step explanation:

x = 7, 11, 14  

y =  4, 18

x = 7, 19, 11 , 5, 14

23-7 = 16  and  23-11 = 12  and  23-14 = 9

y = 14, 4, 12, 18, 9

therefore

y = m x + c

y - 16 =  -16 (x + x1)

y - 16 = -16x + 7)

y -16 + 16   =  -16x + 7+16

y = -16x + 23

which proves y coordinate rests on 23 toys when x = 0.

Any number sentence or equation could be done, but this sentence is an equation of the line and represents.x + y on the graph.
