Answer:

the vertex (-2, -1)

Step-by-step explanation:

y = 3x² + 12x + 11

Rewrite the equation in vertex form.

3(x + 2)² - 1

set y equal to the new right side

y = 3(x + 2)² - 1

Use the vertex form, y = a(x-h)² + k

a = 3

h = -2

k = -1

therefore,

the vertex (-2, -1)

Answer:

$\boxed {m = -\frac{5}{7}}$

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

First Point: $(x_{1} , y_{1})$

Second Point: $(x_{2}, y_{2})$

-Substitute both points:

First Point: $(5, 11)$

Second Point: $(19, -1)$

$m = \frac{-1 - 11}{19 - 5}$

-Solve for the slope:

$m = \frac{-1 - 11}{19 - 5}$

$m = \frac{-10}{14}$

$\boxed {m = -\frac{5}{7}}$

Therefore, the slope is $-\frac{5}{7}$
