PLEASE HELP!! what will happen to the graph of the line y= 3/4x -7 if you change 3/4 to -3/4?

a) the line will intersect

b) the slope of the line will change from positive to negative

c) (4,-4) will become a point on the line

d) the y-intercept will change from negative to positive

Factor this polynomial completely x^2-64

Polynomial that can be factored as (3x-4)(3x+4)
