AA residual
BY-intercept
CThe slope
DCorrelation
Answer & Solution
Correct answer: B. Y-intercept
1. The two coefficients of a straight line play different roles.
2. For the linear equation y = a + bx, b is the slope and a is the y-intercept.
3. The y-intercept is where the line crosses the vertical axis.
4. Confusing it with the slope is the standard error here.
