    Quadratic Formula & Slope of a line Question

    Hello, I have two questions that I can't figure out. I wanted to see if someone else can help me.

    1.) Using the quadratic formula solve the following equation:
    3x^2 -6x=5




    2.) Find the slope of the line passing through the following points (-2,3) and (-5, -1)

    a) The quadratic formula is

    x_{1,2}=\frac{-b\pm\sqrt{\Delta}}{2a}, where \Delta =b^2-4ac

    Here, a=3, \ b=-6, \ c=-5

    b) The slope is m=\frac{y_1-y_2}{x_1-x_2}
