WOAH…. I think maybe it’s…

y = (1/4)(1/5)x Home

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
