In the coordinate plane a slope of the line K is 4 times the y-intercept of the line K. What is the x-intercept of the line K?

A. -4

B. 4

C. -1/4

D. 1/4

E. 2

*An answer will be posted in 2 days.

\(y=mx+h\), but \(m = 4h\). So, we have \(y = (4h).x + h\).

Let´s find the X-intercept of the line K:

In this case, \(y = 0\). Thus, \(0 = (4h).x + h\). Solving this equation we will find \(x = -\frac{1}{4}\)

The correctt answer is letter (

C).
