    y + 6 = 1(x + 3) y + 1 = −1(x + 2) y − 6 = −1(x + 3) y − 6 = 1(x − 3)

    I'd ask @Baseballguy101 He's good at this stuff.

    ok it's y-y1 = m(x-x1). what do you think we shoud do from here?

    6+2=m(1-3) idk

    ok so with your equation being y-y1 = m(x-x1), m being slope, we will need to find this. Do you know how?

    Given two points \((x_1,y_1),(x_2,y_2)\) first find the slope given by \(m=\dfrac{y_1-y_0}{x_1-x_0}\) and then choose any point (say the first one) and we have \[y=m(x-x_1)-y_1\]
