The slope of the straight line is m and the intercept is b. When x is equal to 0, the equation becomes y = m*0 + b, or y = 0 + b = b. y = f(x) = 3.104 * x - 6.090 or y = 3.1 * x - 6.1 The best CURVE fitting quadratic equation for the above set of 8 points, i.e. (x, y) pairs is: f(x) = y = 0.416 * x*x - 0.641 * x + 0.152 2 or y = 0.416 x - 0.641 x + 0.152
