What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

Its worth 10000000 points need asap if you answer correctly ill mark brainliest

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
