Use the diagram to answer the questions. is line m parallel to line n? explain. is line m perpendicular to line k? explain.

The line m is not parallel to line n.

The line m is  perpendicular to line k.

Step-by-step explanation:

The slope of a line can be calculated with the formula

 Choose any point of each line and calculate the slope of each one of them:

Line m:

Line n:

Line k:

The lines m and n are not parallel because their slopes are different.

The line m is  perpendicular to line k because their slopes are opposite reciprocals.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
