Question

What is the equation of the line that passes through the points (−2, 3) and (2, 7)?
x − y = −1
x − y = −2
x − y = − 5
x − y = − 6

Answer 1

@imqwerty

Answer 2

put the points in the equations given in options
the one which satisfies both is the answer :)

Answer 3

idk how to

Answer 4

or u can do it like this-
equation of a line passing through (x1,y1) and (x2,y2) is given by-

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

Answer 5

ok

Answer 6

:)

Answer 7

y2-y1/x2-x1 to find the slope, once found use y-y1=m(x-x1)

Answer 8

im stuck

Answer 9

are you stuck at the beginning?

Answer 10

yea

Answer 11

ok
so we got the equation lets put (x1,y1) and (x2,y2)
\[\frac{ y-3 }{ 7-3 }=\frac{ x- (-2)}{ 2-(-2) }=>\frac{ y-3 }{ 4 }=\frac{ x+2 }{ 4 }\]\[y-3=x+2 =>x-y=-5\]

Answer 12

ok i see it now , i just needed to see how to put it in form

Answer 13

so its c?

Answer 14

yes (:

Answer 15

ty

Answer 16
