Y = kx
-5 = k (2)
k = -5/2

when x = 8
y = kx
y = -5/2 * 8
y = -20

answer is y = -20 when x=8

What is the distance in units from (2, - 12) to (-11, - 12) on the coordinate place?

mezya [45]

Answer:

B: 13

Step-by-step explanation:

we are given two points as

(2, - 12) and (-11, - 12)

so,

$x_1=2,y_1=-12$

$x_2=-11,y_2=-12$

now, we can use distance formula

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

now, we can plug values

$d=\sqrt{(-11-2)^2+(-12+12)^2}$

$d=\sqrt{(-11-2)^2+0}$

$d=13$

So,

The distance is 13
