Question

Line C and D are perpendicular. If the slope of a line c is -4, what is the slope of line D?

Answer 1

`\frac {1}{4}` is slope for line D

Explanation:

Step 1: Find the slope of the line D

Flip the sign on Line C

-4 was previous

4 is new

Convert to reciprocal

4 was previous

1/4 is new

Answer:
`\frac {1}{4}` is slope for line D

Answer 2

1/4

Explanation:

The slope of a line is the steepness of a line.

The slope of a perpendicular line is always the negative reciprocal of the slope of the line it is perpendicular with.

Since line C has a slope of -4, the negative reciprocal of that is 1/4.

Reciprocals are two numbers that multiply together to get 1.

For example, -1/4*-4/1=1

Therefore the negative recipricol is 1/4
