I don't know how to do this I'll give BRAINLEST

A)

Line 1 slope = 3

Line 2 slope = 3

Line 3 slope = 3/-9

B)

Line 1 and 2 are parallel

Line 1 and 3 are Perpendicular

Line 2 and 3 are Perpendicular

Step-by-step explanation:

Use the formula

Line 1, we do   = =

Line 2, we do

Line 3, we do  

now put the lines into point slope formula to get the line. : y-y1 = m (x-x1)

line 1 is   y-4 = 3 (x+1)

line 2 is  y-1 = 3 (x+0)

line 3 is  y+3 = -3/9(x+6)

this is what the graphs look like

red is line 1

green is line 2

black is line 3

answer: ask

step-by-step explanation:

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.'
