Option 3
Step-by-step explanation:
Given data set is,
{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}
By using linear regression calculator,
Equation of the linear function will be,
y = 2x - 2
Therefore, Option 3 will be the correct option.
x -2y -2=0
using the formula, m= ( Y2 - Y1)/( X2-X1)
the gradient is found. the coordinates chosen are (2,0) and ( 0,-1)
the equation of the line is obtained using the formula
y -y1= m(x -x1)
