Y=mx+b, m=delta y / delta x...from the table we can see that m=3/2 so our equation becomes:
y=3x/2 + b, using any point, I'll use (2,2) we can now solve for b, or the y-intercept...
2=3(2)/2 +b
2=3+b, b=-1 our line is thus:
y=1.5x-1
The total number of handshakes was 234.
- The first man shook hands with 12 other men.
- The second man shakes hands with 11 other men, as he had already shaken hands with the first man.
- Like-wise, the last man does not need to shake hands again as every man has already shaken hands with him in their respective turns.
- The number of handshakes among men is 0 + 1 + 2 + … + 12.
- The sum of "n" natural numbers = (n)(n+1)/2
- The number of handshakes among men is 12(13)/2.
- The number of handshakes among men is 78.
- Each man shakes hands with every woman except his spouse.
- Each man shakes hands with 12 other women.
- The number of handshakes between men and women is 13*12.
- The number of handshakes between men and women is 156.
- The total number of handshakes is 78 + 156.
- The total number of handshakes is 234.

Step-by-step explanation:
So for this problem, the x-axis is the horizontal line in the center.
Go to where -2 is on the x-axis as shown. Use your finger to trace along since that's usually helpful in finding the point.
Move your finger from -2 on the x-axis to where the solid black line is. On the right side of that, you can see that the y-axis holds the number 2 which is what the y equals for this solid line.
Therefore, the answer should be c.) y = 2
4x^2-8=136 subtract 136 from both sides
4x^2-144...this is a difference of perfect squares so
(2x+12)(2x-12)
x=±6 or as they put it:
{-6, 6}
