Hello,

we are going to use the theorem of the bissectrice. (if this word is good in english)

$\dfrac{KL}{LM} =\dfrac{KN}{NM} \\\\\dfrac{8}{x} =\dfrac{14}{20-x} \\\\8(20-x)=14x\\\\160-8x=14x\\\\22x=160\\\\x=\frac{160}{22} \\\\x=\frac{80}{11} \\\\\\x=7.\overline{27}$

X h(x) -2 -10 -1 -7 0 -4 1 -1 2 2 What is the y-intercept?

aev [14]

The y-intercept exists where x is 0. In our table, the y value is -4 when x is 0. So that's the place where the graph will go through the y axis. (0, -4) with -4 being the y-intercept.
