Hello I need help not sure if I got it incorrectly

The first row of the table shows (x,y) = (-4,2). If we add in (-4,1), then we will re-use x = -4 a second time. The input x = -4 leads to multiple outputs of 2 and 1 at the same time. Visually the two points stack on each other to form a vertical line, therefore failing the vertical line test.

The second answer choice (1,-4) looks like your teacher might be trying to trick you or place out a trick/trap answer due to how similar it looks. This point can be added and the function is still valid because x = 1 hasn't been used yet in the table.

The answer to your question is there are 440 students

Step-by-step explanation:

Data

110 girls = 25% of the total students

The Total number of students = ?

Use a rule of three to solve this problem

                    110 girls 25%

                      x            100%

                      x = (100 x 110) / 25

                      x = 440 students
