WebReturns the slope of the linear regression line through data points in known_y's and known_x's. The slope is the vertical distance divided by the horizontal distance between any two points on the line, which is the rate of change along the regression line. Syntax. SLOPE(known_y's, known_x's) The SLOPE function syntax has the following arguments: WebSlope–intercept form or Gradient-intercept form [ edit] A non-vertical line can be defined by its slope m, and its y -intercept y0 (the y coordinate of its intersection with the y -axis). In this case its linear equation can be written If, moreover, the line is not horizontal, it can be defined by its slope and its x -intercept x0.

"WebFeb 21, 2024 · A linear gradient is defined by an axis—the gradient line —and two or more color-stop points. Each point on the axis is a distinct color; to create a smooth gradient, the linear-gradient () function draws a series of colored lines perpendicular to the gradient line, each one matching the color of the point where it intersects the gradient line.
