Combinations is when order doesn't matter.
Since there are two identical gift cards, it doesn't matter who gets the first gift card and who gets the second gift card, so this is a combination
There are 5 people choose 2
n!
--------
r!(n − r)!
where n is the number of items and r is how many we choose
5! 5*4*3*2*1
-------- = ------------------ = 10
2! (5-2)! 2*1 ( 3*2*1)

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/2) = -1......(
perpendicular to a line with a slope of -3/2)
a = 2/3 y=(2/3)x+b
the line that passes through (-2, -2) :- 2 =
(2/3)(-2)+b
b = -2/3
<span> the equation is : y = (2/3)x-2/3</span></span>
<span><span>y =(2/3)(x-1)</span></span>
