Can a y intercept be negative

WebPurplemath. In the equation of a straight line (when the equation is written as " y = mx + b "), the slope is the number " m " that is multiplied on the x, and " b " is the y - intercept (that is, the point where the line crosses the vertical y -axis). This useful form of the line equation is sensibly named the "slope-intercept form". WebThe negative intercept tells you where the linear model predicts revenue (y) would be when subs (x) is 0.
