    can you find the slope of the line?

    once you have the slope, equation of line is: \[y - y_1 = m(x - x_1)\] \[(x_1 , y_1) = (0,-5)\]

    you will find the slope using \[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\] just substitute you points.. so lets say that your first x coordinate is 0, and your first y coordinate is -5. the points (-4,-10) will be your second x and y coordinate...

    \[slope = m = \frac{y_2 - y_1}{x_2 - x_1}\] rise over run
