1 Write a function for the table. x-2012 y1/801/201/54/516/5

1 WOAH…. I think maybe it’s… y = (1/4)(1/5) x Home

2 The sum of three consecutive odd integers is -63. Find all three integers.

2 Grrr… Why do you bother me with these silly questions?!?! The answer is obviously -23, -25, and -27.

3 Write the equation of a line in standard form that goes through the points (-3, 6) and (4, 2).

3 I definitely know this… I’m so smart!!!! It’s 4x + 7y = 30!

4 Tickets to the 8 th grade dance are $6 when purchased in advanced and $8 when purchased at the door. If 250 tickets were sold for a total of $1,680, how many tickets were sold in advance?

4 Uhhh…Why do I always have to get the hard ones??? Hmmm, I’m going to say 90 tickets were sold in advance??

5 Write the equation of a line in slope-intercept form that goes through the point (-6,4) and is perpendicular to the line y = -2x-3.

5 It’s DEFINITELY …no doubt!

6 Solve the absolute value equation, if possible. If it is not possible, explain why.

6 Can I have a hamburger if I get this right? The answer is no solution because an absolute value expression cannot be equal to a negative number.

7 Using a coordinate plane system, the course of two pirate ships can be found by the equations: Find the location where the two ships will meet by graphing.

7 I was out swimming so I saw the exact location where the ships met. It was at (-1,3).

8 Graph the solution set for the following inequality:

8 I’d rather not but if I have to, I’m going to say that the answer is.

9 Graph the following linear inequality:

9 Well my darlings, I’m never wrong so trust me… the answer is on the board!
