So we know the slope has to be -3 and the y intercept is 2. y intercept looks like (0,2). since we know this we automatically can rule out B since it has (0,0).

let’s find the slope of A
-9- -5
-3- - 1
the slope= -4/-2= 2
we know it’s not A because the slope is not -3

let’s find the slope of C
-17- -8
-5- -2
slope= -9/-3=3
we know it’s not C because the slope is not -3. we could directly assume that D is the answer no but we’ll still find the slope just to be sure

let’s find the slope of D
14-8
-4- -2
slope=6/-2= -3

the answer is D!!
