Y=2x+5 is correct in y intercept form. ^this one is the most common^
Y-3=2•(x+1) is correct in point slope form.
Use the point slope formula in which the point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
