(a) red.

6 ways out of 15 = 6/15 = 2/5

(b) white,

4 ways out of 15 = 4/15

That's the complement of (a), so it's 1 - 2/5 = 3/5

(d) red or white.

10 ways out of 15 = 10/15 = 2/3

What is the slope of this line? The coordinates are: (-4,5),(0,6), and (8,8).

Elodia [21]

Answer:

Step-by-step explanation:

we have to use the formula of slope here.

we know,

slope of the line passing through (x1,y1) and (x2,y2) is-

$\frac{y2-y1}{x2-x1}$

Here, the first two points are -

(-4 , 5) and (0,6)

So, the slope will be-

$\frac{6-5}{0-(-4)}=\frac{1}{0+4}=\frac{1}{4}$

So, the slope is-

$\frac{1}{4}$
