Question

Which equation that gives the rule for this table.x: 3, 4, 5, 6y: 10, 11, 12, 13A: Y= -x + 7B: Y = x + 7C:Y = 6x + 7OrD: Y= -6 + 7

Answer 1

To solve this problem we can evaluate te terms in the table in each equation so:

For A) y = -x + 7

we replace (3,10)

$\begin{gathered} 10=-3+7 \\ 10=4 \end{gathered}$

So A is incorrect.

For B) y = x + 7

we replace (3,10), (4,11), (5,12) and (6,13)

$\begin{gathered} 10=3+7=10 \\ 11=4+7=11 \\ 12=5+7=12 \\ 13=6+7=13 \end{gathered}$

So B is the correct answer
