You can easily find the midpoint of two numbers by adding them and dividing by two. This is just taking the average. Since the x- intercepts are (-1,0) and (3,0) use the text box to show how you would get the line of symmetry to be x=2 ​

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.
