Answer:
1. C
2. B
3. D
Explanation:
For all of these, take the simple equation of y=mx+b. Plug in the slope for all the equations, so for 1, it would be y=-1/2x+b, for 2, y=3/4x+b, and for 3, y=-1/5x+b. Then, plug in your given points into the respective equations (the x and y values into their respective spots), and solve them out. You should get fractions as an answer for the b value in your equation, and once you have that, you have your equation. Then, you must plug in every point value from the multiple choice answers into the equation until you find one that doesn't work. Reply to me if you got questions.
