Hi. I have this question im my assignment

Find the equation of the straight lines that pass through the points:

(i) (2, -1) and (-4, -19)

(ii) (0, -1/3) and (5, 2/3)

Where do these two lines meet?

I dont know how to do it. Do I actually have to draw the graph? Or is there some way of finding the equations and intercept using a formula or something?

Thanks
