I need help with 2 and 3
2.The inequalities: Show the work for finding the inequality that defines each segment.
3.A point: Choose a point within the boundaries of the shape, and show algebraically that the point satisfies all of the inequalities

Idk for sure

@mathstudent55 @welshfella can you help me?

this sucks xD none can help me

ok @Keigh2015 can you help at all?

Sorry man I can't help

First find the equations for each of the lines

eg The line joining (4,8) and (9,13) is y = x + 4

how did you get that?

and area under that is y > x + 4

y > x + 4 is 4,8 to 9,3?

now you need to do that for the other 3 lines

no (4,8) to (9,13)

ok so

So if (4,8) to (9,13) is y = x + 4

Then
y2 - y1
------ = (4 - 8) / (9 - 3) = ?
x2 - x1

How would I solve that @welshfella

4-9 and -8+3

ok 4-9 is 5 and -8+3 is -5

no 9-4 and -3+ 8 I believe I mixed them up

thats 5 and 5

so 10?

I swear I'm wrong just ask welsh..xD

wow i cant believe it im so lost rn

is that for 9,3 or 9,13?

that is the equation for the line joining (4,8) and )9,3)

|dw:1440009717505:dw|

there are the slopes of the four lines

wow I just got ignored..:O..well then..bye

|dw:1440009783646:dw|

so for 9,13 to 14,8 is the same then?

sorry - i'm ok in English - not brilliant

so from 9,13 to 14,8 it would be y = -x + ?

yes but you'll need to plug in one of the points - use (9,13)

ok so it would look like

y - y1 = -1(x - x1)
y1 = 13 x1 = 9

you have to always that general form
y-y1 = m(x - x1)

ok so then it would look like this? y = -x + 9

no

y - 13 = -1(x - 9)
now isolate y and simplify the RHS

y - 13 = -x + 9
now add 13 to both sides

13 and 13 so that would be y= - x + 22?

yes

ok so that would be 9,13 to 14,8

we've just done that one

I know

lets see what we've got so far
y = x+ 4
y = -x _ 12
y = -x + 22
oh we haven't done (9,30 to (14,8)

yep

I dont know how to start it

I 'll have to look the stuff over again I'm not sure if i'm right.
Give me a minute

so theres the equation for 4 lines
y = x+ 4
y = -x + 12
y = x - 6
y = -x + 22

thanks so much

gotta go

ok thanks so much
