Which three ordered pairs complete the table to give solutions of the equation y = x – 7?
a.(3, –10), (0, –7), and (3, 4)
b.(–3, –10), (0, –7), and (3, –4)
c.(–3, –4), (0, –7), and (3, –4)
d.(–3, 4), (0, –7), and (3, –4)

The answer is   B.(–3, –10), (0, –7), and (3, –4)  
y = x - 7

According to the table: 
- When x = -3, then y = -3 - 7 = -10. So the pair is (-3, -10)
- When x = 0, then y = 0 - 7 = -7. So the pair is (0, -7)
- When x = 3, then y = 3 - 7 = -4. So the pair is (3, -4)

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8

Xis -1/2
y is 35/4.
