Its hard to explain math online, but there are tons of smart people that would do their best to help you here. What parts are giving you the most trouble?

The first on you just need to put it in y = mx + b form. They gave you the m. B is what y equals when x is zero, The coordinate has a x as zero, so b would 10. The equation would be y = -1/4(x) + 10.

Another way would be to substitute x, y, and m into y = mx + b and solve for b.



Im gonna have to look up point slope form to remember it better, but its going to be pretty much the same.

The equation is y = m(x - X) + Y, where X and Y are the point that you know. Its going to pretty much look like y = mx + b when you're done substituting.
