Answer:
y= 2/7x+ 43/7
Explanation:
When finding the y intercept, or B, you should use slope intercept and plug in your coordinate. It should look like this: 7=2/7(3) +b. Multiply 3 and 2/7 to get 6/7. Now, this is your equation: 7=6/7+b. Next, subtract 6/7 from both sides to get 43/7. So, your y-intercept is 43/7. This is your final equation: y= 2/7x+ 43/7. Hope this helped!
