The equations x minus 2 y = 1, 3 x minus y = negative 1, x + 2 y = negative 1, and 3 x + y = 1 are shown on the graph below. On
a coordinate plane, there are 4 lines. Green line goes through (0, negative 1) and (1, negative 1). Orange line goes through (negative 1, negative 1) and (0, 1). Pink line goes through (0, 1), and (2.5, negative 1). Blue line goes through (0, 1) and (negative 2.5, negative 1). Which system of equations has a solution of approximately (0.6, –0.8)? x + 2 y = negative 1 and 3 x + y = 1 x minus 2 y = 1 and 3 x + y = 1 x minus 2 y = 1 and 3 x minus y = negative 1 x + 2 y = negative 1 and 3 x minus y = negative 1

Answer:
dy/dx at x=6 is 0.334
Step-by-step explanation:
The center difference method requires that the values of the function are given in equal intervals which is the case, and allows one to find the value for x = 6 using those of the function for x = 5.5 and for x = 6.5 as follows:
