Assessing fraction inputs

I’m having trouble getting this question to accept the correct answer (y=-1/2x+2). I know the issue is my fraction. I have tried everything I know to do, but to no avail. Screen Shot 2020-04-08 at 11.04.56 AM

Here is the link to my activity. I am looking at page 2. Intro to Linear Regression • Activity Builder by Desmos

I figured it out… my number2 was wrong… For anyone looking at this later and struggling like me, I had to use y=-\frac{1}{2}-2

In CL it should be a double backslash. In a graph, single backslash.
