Question 2 is B
To start, we know that Question 2 is in slope intercept form or y = mx + b with m being the slope and b being the y-intercept. Knowing this we also know that if the y-intercept is -3, the point is (0,-3).
Now, we can graph this starting at the point (0,-3) & use the slope which is 1/2 in the form rise/run to find the next point. Go up 1 and over 2. Keep going in that pattern to get the rest of the points.
After doing this we now know the points r, (-12,-9) (-10,-8) (-8,-7) (-6,-6) (-4,-5) (-2,-4) (0,-3) (2,-2) (4,-1) (6,0) (8,1) (10,2)
Next we can check what they have as choices, if all of those points I listed and no others that weren't listed r there, than it is correct. So, knowing this, the correct answer is B. U might think its D or C, but neither of those show ALL the correct possible solutions.
Hope that helps! I'm not completely sure bout the answer to question 3 and I don't wanna give an inaccurate answer :)
(I attached the graph that I plotted the points on)
