I WILL FAN AND MEDAL!

Please don't just give me the answer, explain it if you can because I don't understand.

Choose an answer

Which is an equation in point-slope form for the given point and slope?



Point: (1, –7); Slope: -2/3

A. y-7=2/3(x-1)
B. y+7= -2/3(x-1)
C. y+7=2/3(x+1)
D. y-7= -2/3(x+1)

Answer 1

I think the answer is b but im not sure

Answer 2

@iGreen can you help me?

Answer 3

\(y - y_1 = m(x - x_1)\)

Where \(y_1\) is the y-value of the point, \(x_1\) is the x-value of the point, and \(m\) is the slope.

Answer 4

@iGreen im confused which one would it be?

Answer 5

Plug in:

'-2/3' for \(m\)
'1' for \(x_1\)
'-7' for \(x_2\)

Answer 6

Is the answer B @iGreen

Answer 7

uhh b or c??

Answer 8

Oops, I meant plug in '-7' for \(y_1\)

Answer 9

C has 2/3 in it and not -2/3, so C is incorrect.

Answer 10

@gleahy121

Answer 11

so b?

Answer 12

Yes @gleahy121 if i wasnt c then it will be b because c was my other choice

Answer 13
