For example, a slope of means as the x- value increases (moves right) by 3 units, the y -value moves up by 10 units on average. The y-intercept is the value on the y-axis where the line crosses. For example, in the equation y =2 x – 6, the line crosses the y -axis at the value b = –6. Web22 jan. 2024 · Whenever we perform simple linear regression, we end up with the following estimated regression equation: ŷ = b 0 + b 1 x. We typically want to know if the slope coefficient, b 1, is statistically significant.
