Question

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

Point: (1, –7); Slope: -2/3

Answer 1

@confxsedaf will fan and medal

Answer 2

Given a point (Xa, Ya) and the slope m, you can find the point-slope form with the equation:
y-Ya = m (x-Xa).

Does this make sense?

Answer 3

i think so

Answer 4

y+7=2/3(x+1)

Answer 5

is it that

Answer 6

Almost! check the right side of your equation.

Answer 7

y+7=-2/3(x+1)

Answer 8

Answer 9

(sorry, openstudy is being p slow and irregular about notifications today, must be all the traffic). The portion inside the parenthesis on the left side is just a little wrong. Check it again?

Answer 10

ok

Answer 11

y-7=-2/3(x+1)

Answer 12

Ah, sorry!! I meant the portion inside the parenthesis on the right side. My bad.

Answer 13

ok

Answer 14

y-7=2/3(x+1)

Answer 15

Look at the equation for point-slope form again: y-Ya = m (x-Xa)

Answer 16

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 17

The answer I would give for the point-slope form of the line going through the point (1,-7) with slope -2/3 is the following equation:
y+ 7 = -2/3 (x -1), going by the equation I showed above.

Answer 18

Perhaps you have the point state wrong in the original problem? Otherwise I don't know how else to slice it, because y+ 7 = -2/3 (x -1) is the correct answer (I even verified with Wolfram alpha, http://www.wolframalpha.com/input/?i=%281%2C-7%29+slope+-2%2F3)
