What happens to a line when the y-intercept is changed? Check all that apply

AAs the y-intercept increases, the graph of a line shifts up
BAs the y-intercept decreases, the graph of a line shifts down.
CAs the y-intercept increases, the graph of the line shifts right
DAs the y-intercept decreases, the graph of the line gets less steep
EAs the y-intercept decreases, the graph of the line shifts left

A and B
Reason and proof:
suppose we have the following function
f(x) = 2x + 1
the y intercept is 1 therefor it'll intersect the y axis at (0,1)
however if the function was to be
f(x) = 2x - 1
the y intercept is -1 that means it intersect the y axis at (0,-1)
