Answer:

y = 8x + 70

Step-by-step explanation:

Given :

Games sold (x)  Total earnings (y)

1                              78

2                              86

3                              94

Option A : y = x +8

Since we are given that when x = 1 y=78

So verify the option A

78 = 1 +8

78≠9

Hence option A is wrong

Option B :  y = 8x + 70

Since we are given that when x = 1 y=78

So verify the option A

78 = 8*1 +70

78=78

For x =2 y = 86

y = 8x + 70

86=8*2+70

86=86

For x =3 y = 94

y = 8x + 70

94=8*3+70

94=94

Hence option B is correct

Option C :  y = 8x + 78

Since we are given that when x = 1 y=78

So verify the option A

78 =8* 1 +78

78≠86

Hence option C is wrong

Option D :  y = x + 78

Since we are given that when x = 1 y=78

So verify the option A

78 =1 +78

78≠79

Hence option D is wrong

Hence option B shows the best equation shows the relationship between x and y:  

y = 8x + 70
