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.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
