y ≤ -2x + 2

jimthompson5910 (jim_thompson5910):

if you want to graph this, then step 1) graph the line y = -2x + 2 step 2) make this line a solid line (because we have an underline under the < sign) step 3) shade below the solid line (because we have < as part of the inequality sign)

OpenStudy (anonymous):

umm what we gotta do?

OpenStudy (anonymous):

graph it !

jimthompson5910 (jim_thompson5910):

let me know if my steps help

OpenStudy (anonymous):

is this right??

jimthompson5910 (jim_thompson5910):

you nailed it

OpenStudy (anonymous):

UR THE BEST

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

is this underfined?? What is the slope of the line x = -5?

OpenStudy (anonymous):

undefined

jimthompson5910 (jim_thompson5910):

yes it is

jimthompson5910 (jim_thompson5910):

x = -5 is a vertical line with an undefined slope

OpenStudy (anonymous):

THANMK U SO MICH ONE MORE QUESTION

jimthompson5910 (jim_thompson5910):

go for it

OpenStudy (anonymous):

If the linear function representing the number of laps Jessica swam each week is f(w) = 10w + 8. What does the 10 represent in this function? Week Laps 1 18 2 28 3 38 4 48

OpenStudy (anonymous):

weeks is the first colum, laps is the second

jimthompson5910 (jim_thompson5910):

w is the number of weeks f(w) is the number of laps

OpenStudy (anonymous):

The number of laps Jessica swam in week 0. The week of the summer that Jessica swam. The number of laps Jessica swam in total. The number of laps Jessica increased her swim by each week.

OpenStudy (anonymous):

those are the options

jimthompson5910 (jim_thompson5910):

what happens when w = 1

OpenStudy (anonymous):

then 10 stays the same??

jimthompson5910 (jim_thompson5910):

look at the table or plug in w = 1 into the function

jimthompson5910 (jim_thompson5910):

what is the output?

OpenStudy (anonymous):

i awnser it right !

OpenStudy (anonymous):

thanj u so much !!

jimthompson5910 (jim_thompson5910):

not sure which answer you picked, but the 10 is the slope

jimthompson5910 (jim_thompson5910):

the slope is the rate of change and it says that the rate of change is 10 so that means that the number of laps are going up by 10 each week

OpenStudy (anonymous):

yeah thats what i put ! thanks (: stay on if u can for anymore questions lol

jimthompson5910 (jim_thompson5910):

i can do a few more

OpenStudy (anonymous):

five more ok?? lol

jimthompson5910 (jim_thompson5910):

how about 2

OpenStudy (anonymous):

)':

OpenStudy (anonymous):

okk

jimthompson5910 (jim_thompson5910):

I don't want to do all of your hw for you

OpenStudy (anonymous):

its not homeworkk lol

OpenStudy (anonymous):

i had over 50 questions i already answered lol

jimthompson5910 (jim_thompson5910):

is it a test?

OpenStudy (anonymous):

Which function below has the smallest slope? f(x) f(x) = 2x - 3 or

OpenStudy (anonymous):

or h(x) x h(x) -1 3 1 7 3 11

OpenStudy (anonymous):

and the options are f(x) g(x) h(x) The functions all have the same slope

OpenStudy (anonymous):

and noo its not a test

jimthompson5910 (jim_thompson5910):

I don't see g(x)

jimthompson5910 (jim_thompson5910):

oh wait, is g(x) the visual line graph you just posted?

OpenStudy (anonymous):

yess sir

jimthompson5910 (jim_thompson5910):

what is the slope of f(x)

OpenStudy (anonymous):

6?

jimthompson5910 (jim_thompson5910):

f(x) = 2x - 3

jimthompson5910 (jim_thompson5910):

it's not 6

jimthompson5910 (jim_thompson5910):

hint: y = mx+b has the slope m

OpenStudy (anonymous):

2

jimthompson5910 (jim_thompson5910):

good what's the slope of g(x)

OpenStudy (anonymous):

5?

jimthompson5910 (jim_thompson5910):

start at (0,-5) and try to go to (1,-3)

jimthompson5910 (jim_thompson5910):

you'll find that the slope is not 5, but it is _____

OpenStudy (anonymous):

5, 2.5??

jimthompson5910 (jim_thompson5910):

not sure how you got that

OpenStudy (anonymous):

i went up 5 and to the side 2 and half

jimthompson5910 (jim_thompson5910):

remember that slope = rise/run

jimthompson5910 (jim_thompson5910):

ah i see, how about going up 2, then over 1

jimthompson5910 (jim_thompson5910):

that makes you go from (0,-5) to (1,-3)

OpenStudy (anonymous):

3??

jimthompson5910 (jim_thompson5910):

no you don't add

jimthompson5910 (jim_thompson5910):

slope = rise/run

jimthompson5910 (jim_thompson5910):

you "rise" 2 then you "run" 1 rise = 2 run = 1

OpenStudy (anonymous):

i know, is it 3, 0

OpenStudy (anonymous):

ughh ohhh i see

jimthompson5910 (jim_thompson5910):

no

OpenStudy (anonymous):

so its 2,1?

jimthompson5910 (jim_thompson5910):
