Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (7, 8) into the partial equation
8 = - 21 + c ⇒ c = 8 + 21 = 29
y = - 3x + 29 → A
11/12 of 7 is simply their product.

<h3>
Answer: A) D and H</h3>
These two points are on the front panel along with points A and B
Choice B is not the answer since points A,B,F are on the floor panel, but point I is not on the floor panel (instead its on the right wall panel)
Choice C is not the answer as points G and C are in the ceiling panel, while A and B are in the floor panel and front wall panel.
Choice D is not the answer for similar reasoning as choice B not being the answer.
Points are considered coplanar if they are in the same plane. A plane can be thought of as a flat piece of paper that does not bend or curve.
