Question

Helppppppppp(:Write an equation of the line, in point-slope form, that passes through the two given points.
points: (–17, 8), (3, —2)
(y + 8) = –2(x –17)
(y – 8) = (x + 17)
(y – 8) = –2(x +17)
(y + 8) = (x – 17)

Answer 1

You should do these almost in your sleep.

With the point (-17,8), look first at the x-coordiante. -17 suggests you shoud have x - (-17) = x + 17

Discard 1 and 4

Likewise, you should have y - 8.

Too bad. Both 2 and 3 have that.

Now calculate the slope and see which one matches.

Answer 2

(y – 8) = –2(x +17) that what I got

Answer 3

(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-8)/(-2-8)=(x+17)/(3+17)
(y-8)/(-10)=(x+17)/(20)
y-8=-2(x+17)

Answer 4

Thats what I got thank you for the help you guys!!(:
