Consider the two planes.
in the diagram, the only figure that could be parallel to linec
line a.
line b.
line d.
plane q.

Step-by-step explanation:

In the given figure, you can observe that plane R and plane Q are perpendicular. So, neither of lines inside the plane R can be parallel to line c, because it's placed in a perpendicular plane.

This means that they only line that can be parallel to line c, it's actually line d, because it's in the same plane, and the figure shows that they have the same direction, which allow us to deduct that they are parallel.

understand that i don't know the answers

will someone answer his question

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
