The domain of this function is {-12,-6,3,15}. Y=-2/3x+7

Evgen [1.6K]

Considering the given function, the table is completed as follows:

x|y

-12|15

-6| 11

3|5

15|-3

<h3>Which is the function?</h3>

The function is defined by:

$y = -\frac{2}{3}x + 7$

Hence, when x = -12:

$y = -\frac{2}{3}(-12) + 7 = 15$

When x = -6:

$y = -\frac{2}{3}(-6) + 7 = 11$

When x = 3:

$y = -\frac{2}{3}(3) + 7 = 5$

When x = 15:

$y = -\frac{2}{3}(15) + 7 = -3$

Y-5=-1/2(x+7) (find the slope)

sashaice [31]

It's the slope-point formula:

$y-y_1=m(x-x_1)$

We have:

$y-5=-\dfrac{1}{2}(x+7)$

Therefore, the slope $m=-\dfrac{1}{2}$
