Question

Annie was given two pieces of information and must write the equation of a line crosses the y-axis at the point (0,5) and has a slope of -4 what is the equation of the line?

A) y = 5x - 4

B) y = -5x + 4

C) y = 4x - 5

D) y = -4x + 5

Answer 1

Answer:

D) y = -4x + 5

Step-by-step explanation:

We know a point and a slope.  The point is a special point.  It is the y intercept because x = 0.  We can use the equation for a line in slope intercept form

y= mx+b

where m is the slope  = -4

and b is the y intercept = 5

y = -4x+5
