alright. for this problems our main focus is to be familiarized with the linear equation.

1. y-3 = 2/5 (x+1) we can see that the ordered pair is (-1,3)

plot it to the graph and make a rise over run of 2/5

by doing that you can trail the answer to point A.

2. y = 1/3x + 7 get the y intercept (0, 7) plot it and make a 1/3 rise over run... letter C.

3. try tracing it our by a ruler and see which point passes along. you will see that it is (4,5) D.

4. doping a line using a slope 1/5 you can trace a point (0, -11) which is the yu intercept .B.
