let's quickly find the slope
slope = (-45 - (-21) )/(5-2) = -8
which rules out C and D
Sub (2, -21) into B which is y = -8x + 5 and your choice
LS = -21
RS = -8(2) + 5 = -11
so , Nope, it is not B
Mmmhhh, I wonder .....
The ordered pairs (2, -21) and (5,-45) are solutions to which of the following equations?
A. y = -8x - 5
B. y = -8x + 5***
C. y = 8x - 5
D. y = 8x + 5

Thank you!
do you mind if I ask another?
which is a rule that describes the translation of a point form (4, -8) to (7, -10)?
A.(x,y) --> (x + 3, y - 2)
B. (x,y) --> (x + 3, y + 2)
C.(x,y) --> (x - 3, y - 2)***
D.(x,y) --> (x - 3, y + 2)
A.(x,y) --> (x + 3, y - 2)
B. (x,y) --> (x + 3, y + 2)
C.(x,y) --> (x - 3, y - 2)***
D.(x,y) --> (x - 3, y + 2)
hmmm. does 4-3 = 7?
no so would it be a?
correct
The answer is A
