The table shows the relationship between the number of members in a group and the minuted each member speaks during the presenta
tion (2, 11), (3, 8), (4, 5), (5, 2). Is the relationship a function that is increasing or decreasing? Is the relationship a function that is linear or non linear
The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7 => a= -2 Passes through (4,1) => x=4, y=1 Substituting into the equation: 1= -2x(4) + b => b= 9 => y= -2x + 9
