you don't say which is x and which is y, but assuming they are x,y respectively, then start with the intercept form of the line.
x/2 + y/1 = 1
now rearrange things into the desired form.

or, since you already know that the y-intercept is 1, you have
y = mx+1
now plug in the other point, and you have
0 = 2m+1
now finish it off
