The y-intercept is the b term in slope intercept form (y = mx + b) or in the form of a point (0, y).
Function 1 is in slope-intercept form, and the b term is 5.
Function 2 is given in a table, but it is easy to find the point (0, y) and y is 5.25.
5.25 > 5
Function 2 has the greater y-intercept.
Hope this helps!
