A line has a slope of - 4 and a y-intercept of 1. What is the equation of the line in slope-intercept form?

A. Y=x-4

B. Y=-4x+1

C. Y=4x+1

D. Y=-x+4

The answer is B because the equation is y=mx+b, where m is the slope and b is the y intercept. In this case m or the slope is - 4 and the b or the y intercept is 1 so then just substitute them in and there is your answer
