Quizplus · Accepted Answer

The regression line is calculated using the formula $ y = a + bx $, where $ b $ is the slope and $ a $ is the y-intercept. Calculating these from the given data, the slope $ b $ is approximately 2.4 and the intercept $ a $ is approximately 1.2, leading to the equation $ y = 1.2 + 2.4x $.

A) Y = -24 + 1
