Which is the equation of the given line in slope-intercept form?

OpenStudy (anonymous):

I believe its D but im not sure... check?

OpenStudy (anonymous):

:I

OpenStudy (igreen):

Incorrect..first find the slope.

OpenStudy (igreen):

(-1, 5) and (1, -1) are the points given, plug them into the slope formula. \(m = \dfrac{y_2-y_1}{x_2-x_1}\) \(m = \dfrac{-1-5}{1+1}\) Simplify that

OpenStudy (anonymous):

4/2

OpenStudy (igreen):

No..-1 - 5 isn't 4..

OpenStudy (anonymous):

Oh my bad 6

OpenStudy (igreen):

Nope

OpenStudy (anonymous):

.. oh -6

OpenStudy (igreen):

Yep, now divide -6 / 2

OpenStudy (anonymous):

-3

OpenStudy (igreen):

Yes, so the slope is -3. So far we have: y = -3x And only one of them start off like this, so which one should be your answer?
