Answer 1

ok

Answer 2

Do you know how to calculate the slope? @Carson15

Answer 3

I'll throw in colors for you

\(\Large\text{Slope} = \dfrac{\color{green}{y_2} - \color{orange}{y_1}}{\color{cyan}{x_2}-\color{red}{x_1}}\)

where you have two points
\(\Large (\color{red}{x_1}, \color{orange}{y_1})\) and \(\Large (\color{cyan}{x_2}, \color{green}{y_2})\)

So you're two points are

\((\color{red}{1}, \color{orange}{4})\) and \((\color{cyan}{3}, \color{green}{-2})\)

Answer 4

alright, answer is C. correct?

Answer 5

just worked it out and thats what i got. just running it by u to make sure i didnt mess up

Answer 6

no

you've calculated the slope, but remember they're asking for a line that's perpendicular to that and goes through (3, -5)

Answer 7

the slope of the perpendicular line will be the opposite reciprocal

Answer 8

so if the slope is 2 then the OPPOSITE of that is -2 and the RECIPROCAL would make it -1/2

Answer 9

so what is the slope between the two points?

and then what would that make the slope of the perpendicular line?

Answer 10

think it would be a since it would be the opposite reciprocal.....if not a

Answer 11

B*

Answer 12

so the equation is

y = -1/3 x + b

we need to calculate `b` by plugging in (3, -5)

so

-5 = -1/3 *(3) + b

what is b =

Answer 13

-1?

Answer 14

I made a typo, you got the slope of the perpendicular line as 1/3 which is correct

so we have

-5 = 1/3 *(3) + b

what is 1/3 * 3 =

Answer 15

oh lol....1

Answer 16

im assuming the answer is A.

Answer 17

yes, sorry

so 1/3 * 3 = 1

so now we have

-5 = 1 + b

what is b =

Answer 18

its ok lol.....umm, -6 right?

Answer 19

yee

Answer 20

alright, thx

Answer 21

No problem
