Answer:

B. y=1/2x-5

Step-by-step explanation:

From the graph, we read the slope of line JK.

slope = rise/run = -3/-6 = 1/2

The equation we need has the same slope.

y = mx + b

y = (1/2)x + b

It passes through point P(6, -2). Now we find b.

-2 = (1/2)(6) + b

-2 = 3 + b

b = -5

The equation is

y = (1/2)x - 5

In triangle xyz what is the cosine ratio of angle x

Jobisdone [24]

Data:
Hypotenuse is 7.5
Opposite of angle x is 6

Cosine = Side opposite (S.O) the angle on the hypotenuse (h)

We have:

 $Cos (\alpha)x = \frac{S.O}{h}$
$Cos (\alpha)x = \frac{6}{7.5}$
$\boxed{Cos (\alpha)x = 0.8}$
