Question

Which graph matches the equation y+3=2(x+3)?

Answer 1

Answer:

A (0,3) (-3,-3)

Step-by-step explanation:

A graph will match the equation if both the coordinates points replaced in the equation generate a identity.

When x = -3

$y + 3 = 2(x + 3)$

$y + 3 = 2(-3 + 3)$

$y + 3 = 0$

$y = -3$

So (-3,-3) is part of the graph.

When x = 0

$y + 3 = 2(x + 3)$

$y + 3 = 2(0 + 3)$

$y + 3 = 6$

$y = 3$

So (0,3) is part of the solution.

(-3,-3) and (0,3), so option A.
