A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
We can employ some logic to reduce the answers we need to test. We know that the slope perpendicular to line l has to have a negative reciprocal slope, so a slope of
. We see that in A and C, as x increases so does y. That means the slope of these equations are positive, which we don't want. Now for some algebra:

We se that D has the correct slope so that must be the answer.
Answer:
16
Step-by-step explanation:
3(2+4)-(3-1)=
3 x 6 - 2=
18 - 2 =
16
Answer:
Put it in between the 0 and -1. Put it on the last line closer to the -1 but not on the -1.
Step-by-step explanation:
This is because 3/4 in general is less than one.
This is how it looks on a graph.
