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

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