Question

what is the equation of this graph

Answer 1

it has two lines
x+y=1 (x<=4,y<=3)

and

x+y=7 (x>=4,y<=3)

Answer 2

what is the equation and how did you get it @mathmath333

Answer 3

i am little confused here

@aum

Answer 4

pick up any two points and
use formula y=mx+c for two lines

Answer 5

-2,-2 and 7,0

Answer 6

for first line pick(1,0) and (4,3)

for second u many pick (7,0) and (4,3)

Answer 7

ok

Answer 8

Answer 9

This one is a bit tricky.
you could find the equations of two different lines
the slopes are -1 (down and to the left)
and +1 (up and to the right)
you would find

y= -x + 7, x>= 4
y = x +1 , x<= 4

but, we can use the y= |x| graph
to make one equatoin

Answer 10

**y= -x + 7, x>= 4
y = x -1 , x<= 4 ** fixed typo

Answer 11

But they probably want you to know that the "parent function" y= |x| is a v shaped graph made by two lines with slope of 1 and -1.
they you reflect graph about the x-axis (by multiplying by -1)
shift right (replace x with x-4 )
and shift up by 3 (add +3)
y = -|x-4| + 3

Answer 12

great!
