do you want us to add, subtract, multiply, divide...what..?
Answer:
y = -2x - 2
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -2
so now the equation is y = -2x + b
from here, what you could do to find b is...
plug (-2, 2) into the equation
1) x = -2, y = 2
2) 2 = -2(-2) + b
3) 2 = 4 + b
4) -2 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -2)
so "b" would be equal to -2
this makes the final equation y = -2x + (-2) or y = -2x - 2

Step-by-step explanation:
3 1/4 ÷ 1/3 = 9 3/4
There are 10 pairs of shoes. 8 shoes are select.
<span>P = (2/20) (2/19) (2/18) (2/17) (2/16) (2/15) (2/14) (2/13) </span>
<span>P = 2^8 / (20P8) </span>
<span>But, any 8 differents shoes can be chosen from 10 pairs. </span>
<span>so there are 10C8 = 45 ways to do so </span>
<span>P = 45 * 2^8 / (20C8) </span>
<span>But, since order does not matter, there are 8! way you can select the 8 different shoes </span>
<span>P = 8! * 45 * 2^8 / (20C8) </span>
<span>P = 384/4199 or about 9.145%</span>
