dumbcow · Answer

can you find the slope of the line?

dumbcow · Answer

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

I'm confused.

Hello @cheymariee  , do you still need some help?

anonymous · Answer

Yes I do.

en · Answer

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...

dumbcow · Answer

$$slope = m = \frac{y_2 - y_1}{x_2 - x_1}$$
