Complete the equation of the graphed linear function. Write the slope in decimal form. y =___x +___ https://static.k12.com/calms_media/media/1522000_1522500/1522150/1/72228027290231c1fc28ce3670bacc7155cce378/MS_IMC-140829-100652.jpg @susanna

OpenStudy (susanna):

find the slope first.

OpenStudy (susanna):

(0, -1) and (2,0) are the two points I could easily make out.

OpenStudy (anonymous):

i'm in a hurry bro. my mum is checking. and i somehow missed this one

OpenStudy (susanna):

the slope is 1/2

OpenStudy (anonymous):

i can calculate

OpenStudy (susanna):

y-0=1/2(x-2) y=1/2x-1

OpenStudy (anonymous):

thanks. i think there's one more

OpenStudy (susanna):

sure

Complete the equation of the graphed linear function in point-slope form. y – 8 =___ (x –___) https://static.k12.com/calms_media/media/1522000_1522500/1522153/3/b9695124bd99b2284dab287b469d8a032e021858/MS_IMC-140829-100655.jpg

OpenStudy (susanna):

the slope is -2

OpenStudy (susanna):

WAIT that was wrong

OpenStudy (anonymous):

okay lol

OpenStudy (susanna):

(8, -4) so the final answer is y-8=-2(x+4)

OpenStudy (anonymous):

how da hell did i still get a 40

OpenStudy (anonymous):

it wasn't 4, it was 2

OpenStudy (anonymous):

alright. let's try this again

OpenStudy (susanna):

oh, I know what I did wrong

OpenStudy (susanna):

I saw the y-8 part and messed up. The point is actually (2,8), not (8, 4) I mixed up the y and x in the points. I'm sorry...

OpenStudy (susanna):

y-8=-2(x-2) THAT is the answer

OpenStudy (anonymous):

Which equation represents the graph of the linear function? A. y= -1/3x + 1 B. y=-3x - 1 C. y=3x + 1 D. y=-3x + 1

OpenStudy (susanna):

It's D

OpenStudy (anonymous):

Which equation represents the graph of the linear function? A. y = 4x + 4 B. y = 4x − 4 C. y = −4x + 4 D. y = −4x − 4 https://static.k12.com/calms_media/media/1524500_1525000/1524543/1/a1813a17f6398a013af664632a476db2e7ec0607/MS_IMC_06_05_116090.jpg

OpenStudy (susanna):

It's B

OpenStudy (anonymous):

Which equation represents the graph of the linear function? A. y = 3x B. y = 3 <--- my answer C. y = −3 D. y = −3x https://static.k12.com/calms_media/media/330000_330500/330016/1/df3d84234480072bf50451965634ce787bc08bf8/MS_ALG_S2_01_04_quiz_Q3_question.gif

OpenStudy (susanna):

you're right

OpenStudy (susanna):

slope is -0.75

OpenStudy (susanna):

y=-0.75x-4

Complete the equation of the graphed linear function in point-slope form. y – (–2) =___ (x –___ ) https://static.k12.com/calms_media/media/1522000_1522500/1522154/1/b46c3a188a94fdd3b92220d260520511848f250c/MS_IMC-140829-100656.jpg

OpenStudy (susanna):

slope is 4

OpenStudy (susanna):

y-(-2)=4(x-1)

OpenStudy (susanna):

can you open a new post?

OpenStudy (anonymous):

so is that a negative or positive one?

OpenStudy (susanna):

that's a positive 1

OpenStudy (anonymous):

that was also the last one

OpenStudy (susanna):

but it's subtracted

OpenStudy (anonymous):

kay good

OpenStudy (anonymous):

FINALLY. AN 80. THANK YOU

OpenStudy (susanna):

no prob

OpenStudy (anonymous):

Okay bye now. if i need anything else, i'll be back online

OpenStudy (susanna):

sure, but I don't like giving direct answers, so next time I hope you have enough time for me to lead you to the answer.

OpenStudy (anonymous):

Okay thank you. hopefully i will
