Answer:
-1000
Step-by-step explanation:
-10 times -10 makes 100 as negative cancel each other
100 times -10 make -1000
Start by cross multiplying:
41*2 = 5x
Simplify:

The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).
So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5
This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)
Equation is y=mx+b so solve for m with the equation m=y2-y1/x2-x1. so m= -1-7/-2-4. m=4/3.
y=4/3x+7
