To find x intercept, you must set the y value equal to zero
0= -2x+4
Subtract 4
-4= -2x
Divide by -2
x=-4/-2= 4/2= 2
The x intercept is 2
To find the y intercept, you must set the x value equal to zero
y= -2(0)+4
y=4
The y intercept is 4
the answer is 3. after taking 2 socks, you will either have 2 that match or 2 that differ. to ensure a matching pair, you need to add 1 more sock.

8 + 11 = 40
there is a pattern. 1+4=5, the answer from the previous equation 5+2+5=12, 12+3+6=21, 21+8+11=40.
8+11=40
