The graph of the equation y − 1 = −2(x − 2) contains which set(s) of ordered pairs? Select all that apply.

Mila [183]

Answer:

OPTION B.

OPTION C.

Step-by-step explanation:

Given the equation of the line:

$y - 1 = -2(x -2)$

We can substitute the coordinates of each set of ordered pairs into the equation in order to know which belong to the graph of that equation:

A. $(0, -2)\ and\ (1, 3)$

Substituting into the equation these coordinates:

$x=0\\\\y=-2$

We get:

$-2 - 1 = -2(0 -2)\\\\-3\neq 4$

The graph of the given line does not contain this set of ordered pairs.

B. $(0, 5)\ and\ (-2, 9)$

Substituting into the equation these coordinates:

$x=0\\\\y=5$

We get:

$5 - 1 = -2(0 -2)\\\\4=4$

Substituting into the equation the coordinates of the other ordered pair:

$x=-2\\\\y=9$

We get:

$9 - 1 = -2(-2 -2)\\\\8=8$

<em> The graph of the given line contains this set of ordered pairs.</em>

C. $(-1, 7)\ and\ (2, 1)$

Substituting into the equation these coordinates:

$x=-1\\\\y=7$

We get:

$7- 1 = -2(-1 -2)\\\\6=6$

Substituting into the equation the coordinates of the other ordered pair:

$x=2\\\\y=1$

We get:

$1 - 1 = -2(2 -2)\\\\0=0$

<em>The graph of the given line contains this set of ordered pairs</em>

D. $(3, -1)\ and\ (2, -1)$

Substituting into the equation these coordinates:

$x=3\\\\y=-1$

We get:

$-1 - 1 = -2(3 -2)\\\\-2=-2$

Substituting the other ordered pais (2, -1):

$-1 - 1 = -2(2 -2)\\\\-2\neq 0$

The graph of the given line does not contain this set of ordered pairs.
