Identify the slop and the y-intercept of each line. having trouble calculating the slop so i was wondering what i did wrong if i did do something wrong.

My teacher taught me rise over run. So, line A goes up one and to the side 4. That makes the slope 1/4. It's positive when the line goes up as you look to the right. C is a positive slope of 2. And D is - 2/3. Other than those two, you did a really good job!
