the y intercept of the first problem is -1 so start the line there. then, go up 1 and over two a few times because the slope is 1/2. then the second one is point slope form. when you transform it to y=mx+b it is y=1/3x+2. now we know that the y intercept is 2, so we start there. the slope is 1/3, so go up one over 3.
