The first test used in screening for HIV infection was the ELISA test, which measured levels of HIV antibodies in a blood sample. In a particular population of 5000 tested individuals, 20 had HIV but tested negative, 980 had HIV and tested positive, and 3992 did not have HIV and tested negative.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
