Which equation is in slope-intercept form?

Slope-intercept form is written as y = m x + b, where m is the slope and b is the y-intercept. In this form, y is already isolated on the left and appears as a linear expression in x. The equation written as Y = m x + b matches this format exactly, so it is in slope-intercept form. The other expressions aren’t in that form as written: Ax + By = C is a general form not solved for y, Y − y1 = m(x − x1) is point-slope form, and X = (Y − b)/m would have to be rearranged to Y = mX + b to become slope-intercept form.
