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

Start by finding the slope: \[slope = m = \frac{ y_2-y_1 }{ x_2-x_1 }\]
then pick ONE of the two points and plug it in for y sub zero:
\[(y-y_0)=m(x-x_0)\]

Answer 2

x - y = -2

Answer 3

is that it

Answer 4

Not quite.

Answer 5

What's your slope (m). Start with that.

Answer 6

x - y = - 6

Answer 7

No. Are you just guessing now or actually working on it? The answer is quite clear when you actually do it.

Answer 8

x - y = -1

Answer 9

Show me your steps.

Answer 10

thats the answer i did it

Answer 11

No. Because if you did it, you would see that it's not the correct answer.

Answer 12

Also that fact that you guessed every possible answer EXCEPT the correct one shows that you didn't try it.
\[slope = m = \frac{ 7-3 }{ 2-(-2) }= \frac{ 4 }{ 4 } = 1\]
\[y-7=x-2 => x-y=-5\]

Answer 13

@abbot you have him the answer away unknowingly !!

Answer 14

@abb0t

Answer 15

I gave up cuz i was getting frustrated. Lol @AravindG

Answer 16

@abb0t a better idea would have been to report this user. I just went through the questions he asked and I was like "These all were happening in Openstudy and no mods noticed o.O "

Answer 17

lol. my bad. thnx for the tip :) @AravindG
