    Slope

    Please let me know if this is correct:

    Find the equation of the line which satisfies the point through the point (0,5) with slope =-2

    y-y1 = m(x-1)=
    y-5=-2(x-1)=
    y=-2x+-7

    Perhaps you meant it, but it should be: y - y_1  = m\left( {x - x_1 } \right).

    Now, with m = -2 and the point being (0,5) we get:

    y - 5 =  - 2\left( {x - 0} \right) \Leftrightarrow y - 5 =  - 2x \Leftrightarrow y =  - 2x + 5

    The slope is clearly fine and you can easily check whether the line goes through the given point by filling it in to see if it satisfies the equation.
