kise_ryouta · Answer

f(x)=−3/2x−2 might be the answer

triciaal · Answer

f(x) = y
y = m x + b
b is the value of y when x = 0 
m is the slope = change in y over the change in x

triciaal · Answer

is the slope positive or negative?
is the value of b +2 or -2 ?

tkhunny · Answer

The y-intercept is clearly -2.  Immediately discard the second choice.
The slope is clearly negative.  Immediately discard the third choice.

kise_ryouta · Answer

yes i already scratched those out that was obvious

tkhunny · Answer

Yet another time, I see that you are totally on top of it.

How did you calculate the slope?

kise_ryouta · Answer

wait i think i could be d

kise_ryouta · Answer

nevermind it is a

tkhunny · Answer

Rise/Run
Change in y / Change in x

Pick two points and calculate it.

tkhunny · Answer

Ah!!!  That;s what I like to hear.  :-)  Off to the next one!

kise_ryouta · Answer

A makes more sense than D

triciaal · Answer

yes A is correct
