a 11 b 1 c 0 d -1
Answers.
1. B -3/7
2.A-4
3.B 1 To find this you need to find the slope first. Which for this, is 1.That is your y intercept. Next, find your X intercept using the formula Y=MX+B and replace the letters with the coordinating numbers. The X intercept will either be positive or negative depending on points you choose.
