Question

Which of the following is the point-slope equation of the line with a slope = -5 and a point of (2, -1)?

A. y - 1 = -5(x - 2)
B. y + 1 = 5(x + 2)
C. y + 1 = -5(x - 2)
D. y - 1 = 5(x + 2)

Answer 1

Do you remember how the point slope equation looked like?

Answer 2

i dont :(

Answer 3

\(\Large y-y_1=m(x-x_1)\)
where m is the slope
(x1, y1) is the given point

Answer 4

use what you were given and plug it into the equation

Answer 5

as (x1,y1)=(2,-1) amd m=-5 n
now put them into the above equation of Zale101

Answer 6

so y+1=-5x+15

Answer 7

how did you get 15?

Answer 8

i plugged in 3 instead of 5
one sec

Answer 9

so y+1=-5x-10

Answer 10

Oh okay, and by the way, you don't need to distribute because your choices aren't distributed. They just want you to plug it and get the signs right.

Answer 11

so its choice c

Answer 12

yes it is C

Answer 13

thank you both!

Answer 14

Good job @Zale101 and @princessS12

Answer 15

y+1=-5(x-2)
y+1=-5x+10

Answer 16

No Problem!
