0.5(4)+c=-1, so c= -3. Therefore, y=0.5x-3.

Step-by-step explanation:
The way to get this is that you put them in fraction form 7/15 and then you make it equal to to x/100 and then divide the known part of the fraction which in this case is 100/15 which gives 6.67 (rounded). After you get that you multiply it by 7 which give you 46.69%
