What is the point slope form of the line with slope −14 that passes through the point (−2, 9)?

Mice21 [21]

Answer:

y - 9 = -14 (x + 2)

Step-by-step explanation:

Point-slope form --> y - y1 = m ( x - x1)

slope = -14

y1 = 9

x1 = -2

Let's put the values all together:

y - 9 = -14 (x - - 2)

y - 9 = -14 (x + 2) ---> final answer

Answer:

$\large\boxed{B)\ -2}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}3(x+y)=12&(1)\\\\\dfrac{x}{2}=3&(2)\end{array}\right\\\\(2)\ \dfrac{x}{2}=3\qquad\text{multiply both sides by 2}\\\\2\!\!\!\!\diagup^1\cdot\dfrac{x}{2\!\!\!\!\diagup_1}=(2)(3)\\\\x=6\\\\\text{Put it to (1):}\\\\3(6+y)=12\qquad\text{divide both sides by 3}\\\\\dfrac{3\!\!\!\!\diagup^1(6+y)}{3\!\!\!\!\diagup_1}=\dfrac{12}{3}\\\\6+y=4\qquad\text{subtract 6 from both sides}\\\\6-6+y=4-6\\\\y=-2$
