Question

Using point-slope form, write the equation of the line that passes through (2, –1) and has a slope of –5.
A.
(y – 1) = –5(x + 2)
B.
(y – 2) = –5(x – 1)
C.
(y + 1) = –5(x – 2)
D.
(y + 2) = –5(x – 1)

Answer 1

given a point (a, b) and slope m
eq of line is
y-b = m (x-a)
can you proceed now ?

Answer 2

ill try thanks

Answer 3

do you know how to plug in the points and the slope?

Answer 4

not really

Answer 5

well you can see that there is y1 and x1 and m right?

Answer 6

idk

Answer 7

it is similar to the x and the y and m is the slope

Answer 8

okay

Answer 9

y1 = y and x1 = x m = slope

Answer 10

are you still confused?

Answer 11

I will help you

Answer 12

yeah :/

Answer 13

well you know that you have the coordinate (x,y) right?

Answer 14

yeah ik that

Answer 15

(2, –1) well that means that the x and the y is actually the x1 and the y1
(x1,y1) so when you plug in the points you can get the answer easily

Answer 16

alright ill try it thanks

Answer 17

and btw the equation is y - y1 = m(x- x1)

Answer 18

i think its A the answer

Answer 19

no quite it is the last one

Answer 20

D ?

Answer 21

I mean second

Answer 22

to the last one
