Question

Which of the following is an equation of a line passing through the points (-1,2) and (-3,-2)?

A) y=1/2x+4 B) y/2=x+4 C) y=2(x+2) D) y-x/2=8

Answer 1

can u find the slope of the line using (-1,2) and (-3,-2) ?

Answer 2

y=mx+b form?

Answer 3

\[slope = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\]

Answer 4

that;s the formula, yes, but what is the slope?

Answer 5

yep ! if u want it that way u can find the slope and go to slope intercept form or
y= mx + b
or u could do it using point slope form..

but before that u must find the slope

Answer 6

(-2)-2/(-3)--1

Answer 7

Answer 8

Is it B?

Answer 9

answer i c

Answer 10

y = 2x +4

Answer 11

\[( x_{1} \ \ \ \ , \ \ \ \ \ \ y_{1} ) \ \ \ ( x_{2} \ \ \ \ \ , \ \ \ \ y_{2})\]
( -1 , 2) ( -3 , -2)

now plug them in to
\[slope = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\]

Answer 12

Or, from your answers it would be y= 2(x+2)

Answer 13

and as suru said the formulae is for slope which is not compolsory to know

Answer 14

can u do that ?

Answer 15

Dageek did u found the slope ?

Answer 16

C?
