find the slope between (0,-4) and (2,-1)

ok I got 3/2 now what

which choice has 3/2 as the slope?

so that's your answer :)

put the information in point-slope form, then change it into slope-intercept form

how do i make it into point slope form

point-slope form is y - y1 = m(x - x1)

I know that but how to I fill that in to then make it slope intercept form

you put the numbers in first, then you can rearrange to make it into slope-intercept

where would I put the numbers

would y and x not y1 and x1 but y and x become 0

also would it look like this y--2=3(x-1)

yes. y + 2 = 3(x - 1). now distribute the 3 into the parentheses

y+2=(3-1)

no, to distribute, you have to multiply 3 with x, and 3 with -1

so y+2=3-3

subtract 2 from each side

would that be the right step

yea

so it's either b or c

so the answer is..?

when i calculate it it comes up with y=3x-1 but that isn't an answer

did i do that wrong

what's -3 - 2?

-5

so a

yup

thanks if I have any other questions I will send you a message

mmk

yes, it's c :)

yes, that's also c

yes. it's c lol.

yes

that's a

how ?

find the slope between (0,0) and (3,2)

ok found it thanks!

yes, b

thanks

perpendicular lines have negative reciprocal slopes. so our line should have a slope of -2/5

now we can put that info into point-slope form

oh lol. you didn't even need to do any math

so its b

yea

or d

well it wouldn't be d. parallel lines share the same slope, so it's either a or c

i think c

it's a

ok how would i get that on my own? step by step

put it into point-slope form, then change it to slope-intercept form

y + 3 = 7(x - 1)
y + 3 = 7x - 7
y = 7x - 10

yes, that's b

ugh. i hate these questions

I almost started to cry when I saw that question

lol. i would plot it out first before i did the distance formula

ok

which do you think?

yes :)

I was think b or c

at most means less than or equal to

so it's not c

and it would be b if it there wasn't a line underneath the inequality

but since there is...it's not b

and we know it's not d...

so it must be...

Solve the following: b + 4 < -8.
A. b < -12
B. b < -4
C. b > 12
D. b > 4

which do you think?

no. what's -8 - 4?

-12

thanks and ok
