Answer first and i will mark brainliest

A) y = 7x - 22

Explanation: First of all, we know it cannot be D, because if the answer was D, the slope would have to be 14. Next, to find the value of b (the y intercept) we have to do 7(3) and we will then get 21. We then must subtract 21 from -1 and get the slope of -22. The reason we subtract is because we must make the x value 0, and since it is 3, we go backwards. Hope this helped!
