Question

What is the equation of the line in slope–intercept form that passes through the point (0, 3) and is perpendicular to the line y = 2x – 6?

Answer 1

y=-1/2 x + 3

Answer 2

Nice dude. I dont understand where to go after you graph the line

Answer 3

if two lines are perpendicular so we have this equation between the slope so \[\frac{m}{m \prime}=-1\]

Answer 4

ooooo i c

Answer 5

in this equation y=ax+b
that b is y-intercept so b = 3
and we have the slope that is -1/2 that we got from the slopes equation so the tottal equation is y =-1/2 x +3

Answer 6

ok cool. I understand better. Thanks alot!
Can you help me witha another one?

Answer 7

On the graph of the equation 6x – y = –1, what is the value of the y-intercept?

Answer 8

you gotta make y alone in one side so 6x – y = –1 should be like this : y=6x+1
so y-intercept is +1

Answer 9

Hell yeah dawg thanks. Do you just like doing math? Wanna do somemore?

Answer 10

maybe .

Answer 11

lmfaooo alright hahah
What is the equation in point-slope form of the line passing through (4, 0) and (2, 6)?

Answer 12

put them in this equation :\[\frac{y-y1}{y2-y1}=\frac{x-x1}{x2-x1}\]

Answer 13

And then just solve?

Answer 14

omg\[\frac{y-0}{6-0}=\frac{x-4}{2-4}\]
\[\rightarrow -2y =6x-24 \rightarrow y=3x-12\]

Answer 15

THANKS DUDE!

Answer 16

Y=3(x-4)?

Answer 17

no it's not necessary even it make the equation harder

Answer 18

oo ok. can you reduce your answer?

Answer 19

what do u mean?

Answer 20

like y=3x-12 is not an option. Which is why im thinking the answer is y=-3(x-4)

Answer 21

both of 'em are true .

Answer 22

oh alright thankss
