Question 179847
{{{graph(300,300,-10,10,-10,10,4x+5,4x-1)}}}
:
find the x intercepts:
:
those are found by setting y = 0
:
0=4x+5--->4x=-5--->x=-5/4
0=4x-1--->4x=1---->x=1/4
:
so we have one point from each equation on the transversal which is the y axis
:
(-5/4,0) and (1/4,0)
:
{{{d=sqrt((-5/4-1/4)^2+(0-0))}}}
:
{{{d=sqrt((-3/2)^2)}}}
:
{{{d=sqrt(9/4)}}}
:
{{{highlight(d=3/2)}}}
