Answer:
Collinear points are points all in one line and non collinear points are points that are not on one line. Below points A, F and B are collinear and points G and H are non collinear. Coplanar points are points all in one plane and non coplanar points are points that are not in the same plane.
Step-by-step explanation:

The volume of the triangluar block is 4 cubic inches. What is the approximate length of y? -- 2.8 inches
First, turn 
into an improper fraction with a denominator of 4, which matches 
.
Now, just add the numerators.
X=15degrees
The angle measurements are 30, 30, and 120 so it is an isosceles
y = -2/3x -3
x=0 y=-3 point (0,-3) over 0 down 3
x=3 y=-2/3(3) -3 =-2-3 =-5 (3,-5) go to the right 3 down 5
