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

idk

step-by-step explanation:

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to
