I Have a few Questions...

OpenStudy (kewlgeek555):

Choose the point-slope form of the equation below that represents the line that passes through the point (-1, 6) and has a slope of -3. y - 6 = -3x - 3 y - 6 = -3(x + 1) y = -3x + 3 3x + y = 3

OpenStudy (anonymous):

y=-6x+3

OpenStudy (anonymous):

i mean -3x

OpenStudy (kewlgeek555):

Thanks. Do you think you could help me with a few other questions?

OpenStudy (anonymous):

sure

OpenStudy (kewlgeek555):

Hold on, for the first one, are you saying y - 6 = -3x - 3?

OpenStudy (ranga):

The point-slope form is: (y-y1) = m(x-x1) So (y - 6) = -3(x + 1) is the correct answer.

OpenStudy (anonymous):

yes, but the question says to put it into point slope form. Y-6=-3x-3

OpenStudy (anonymous):

y=-3x+3

OpenStudy (anonymous):

@range the point-slope form is y=mx+b

OpenStudy (anonymous):

@ranga

OpenStudy (ranga):

Of the 4 choices in the multiple choice answers, the second choice is the correct answer.

OpenStudy (ranga):

No, y = mx + b is the slope intercept form.

OpenStudy (kewlgeek555):

Yeah... y = mx + b is the slope-intercept form - you both had that...

OpenStudy (kewlgeek555):

Well, I guess since you are here @ranga

OpenStudy (kewlgeek555):

Ill ask you.

OpenStudy (ranga):

Go ahead.

OpenStudy (kewlgeek555):

Choose the point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1). y + 3 = -5(x - 2) y - 2 = -5(x + 3) y + 3 = -one fifth(x - 2) y - 2 = -one fifth(x + 3) This one is D, right?

OpenStudy (anonymous):

b

OpenStudy (ranga):

First find the slope: m = (y2-y1) / (x2-x1) = (1-2)/(2+3) = -1/5 Then the point-slope form is: (y-y1) = m(x-x1) (y-2) = -1/5(x+3) So the answer is D

OpenStudy (kewlgeek555):

Sorry, I left for a moment.

OpenStudy (kewlgeek555):

I have another one. @ranga @sammm
