What is the slope of the line parallel to the line 9y + 2x = 54?<br> Select one:

Paraphin [41]

Answer:

The slope is -2/9

Step-by-step explanation:

9y + 2x = 54

Solve for y to get the equation in the form

y = mx+b where m is the slope and b is the y intercept

Subtract 2x from each side

9y + 2x -2x = -2x+54

9y = -2x+54

Divide by 9

9y/9 = -2x/9 + 54/9

y = -2/9 x +6

The slope is -2/9

Parallel lines have the same slope

The distance between points $P_1(x_1,y_1)$ and $P_2(x_2,y_2)$ can be calculated using formula

$P_1P_2=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.$

$AB=\sqrt{(-7-(-11))^2+(8-4)^2}=\sqrt{16+16}=\sqrt{32}=4\sqrt{2}\approx 5.657.$

$AC=\sqrt{(-4-(-11))^2+(4-4)^2}=\sqrt{49+0}=\sqrt{49}=7.$

$CB=\sqrt{(-7-(-4))^2+(8-4)^2}=\sqrt{9+16}=\sqrt{25}=5.$

Then

$P_{ABC}=5.657+7+5=17.657\approx 17.7$

Answer: correct choice is C.

Answer:

If, a = 2 and b = 3

It's not equivalent.

<h3>Diego</h3><h3> $4a + 9b = 7a + 5b - 3a + 4b \\ 4(2) + 9(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 8 + 27 = 14 + 15 - 6 + 12 \\ 35 = 35 \\$ </h3>

It's equivalent.

The correct equation is 4a + 9b.
