Answer:
The parallel line would be y = -x - 6
Step-by-step explanation:
In order to find the parallel line, we must first start with the slope. The slope of parallel lines must be equal. The first line has a slope of -1. Using this and the new point in slope intercept form, we can solve for the intercept.
y = mx + b
2 = -1(-8) + b
2 = 8 + b
-6 = b
Now we can model the equation using that slope and the intercept.
y = -x - 6
The answer for the question shown above is: The shape of the cross section is a triangle.
The explanation is shown below:
Imagine that you have a plane that intersect the rectangular pyramid and it passes through its vertex and it is perpendicular to the base of the pyramid, when you look the cut, you will see a triangle as a cross section.
3,7,11,15,19,23,27,31
32 = 8th term.
The common difference is +4
