1. Okay. So if you look at the y side, you see that they go up by 3. So basically, you would multiply x by 3 and then add by 2 to get the answer. 1 * 3 is 3 + 2 is 5. 2 * 3 = 6 + 2 is 8. And the pattern repeats. The answer is choice #3.
2. To find the equation for this, let’s use the different points to find out which formula works. A couple of the points we can use are (0, -5) and (1, -7). By trying them out, we can see that choices 1 and 3 do not work. However, we see that equation #4 not only works for those 2 points, but others as well. The answer is choice #4.
