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

1/4

Step-by-step 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

is slope for line D

Step-by-step 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

is slope for line D

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
