Slope, y and x intercept

Question

What is the slope, y an x intercept if any for:

 

f(x)=4

Answer 1

f(x)=4

f(x)=mx + b             where m=slope  and point (0,b) is y-intercept

 

So,  slope m=0

       y-intercept b=4

 

Now, x-intercept is the point where y=0:

  f(x) = 0 = 4          [sorry, can't happen]

Since f(x) is a horizontal line at y=4, it never crosses the x-axis (a point where y=0)

Answer 2

f(x) = 4 is a function of the form f(x)=mx+b where m=slope=0 and b = y-axis intercept = 4.  Zero slope means the line is parallel to the x-axis; b=4 means the line crosses the y axis at (0,4).
