    ok the slope is equal to\[\large{\frac{\Delta y}{\Delta x}= \frac{y_2-y_1}{x_2-x_1}}\]

    \[=\frac{11-5}{-2-0}\]

    Lala, we can further simplify it to: \[ = -\frac{7}{2} \] :P

    No it's \[ =\frac{11-5}{-2-0} = -\frac{6}{2}\]

    \[\frac{-6}{2} = -3\]

    y – 5 = –3(x + 2) y – 5 = 3(x + 2) y – 11 = –3(x – 2) y – 11 = –3(x + 2) were the options though :/

    Who wants to learn? :P here is the answer : \[ y – 11 = –3(x + 2) \]
