Question

The graph below shows a line segment MN:

graph of line MN going through ordered pairs negative 2, 3 and 1, negative 3

Which of the following equations best represents the line segment MN?

y = −3x + 2
y = −2x + 1
y = −3x − 2
y = −2x − 1

Answer 1

HI do you think you could post the graph mentioned?

Answer 2

@peachesncream8 yes

Answer 3

If I read the question right are the ordered pairs: ( -2, 3 ) and ( 1, -3 ) ?

Answer 4

@peachesncream8

Answer 5

you can use the formula (y-y1) = m (x-x1) plug in both of the points (-2,3) and (1, -3)

Answer 6

once you plug in the the coordinates you can isolate the variable m which is the slope to fill in the equation y=mx+b

Answer 7

so, ( -3 -3 ) = m ( 1+ 2)

Answer 8

then, ( -9 ) = 3m .......... m= -3

Answer 9

so that leaves down to two answer choices: Y= -3x +2 OR Y = -3x -2

Answer 10

@peachesncream8 the - one?

Answer 11

then substitute in one of the coordinates into the equaation once more and now that you have your slope solve for the equation

Answer 12

@peachesncream8 okay :)

Answer 13

Are by any chance missing any of the answer choices? I tried solving them as well and came up with the following equations: Y= -3x + 0 and Y= - 3x + 9

Answer 14

Good Luck! : )

Answer 15

Answer 16

You can also try finding the slope which will give you the m in the equation y= mx+b

Answer 17

yea finding the slope would've been easier

Answer 18

@peachesncream8 thanks alot
