Question 975230: find the distance between the x-intercept and y-intercept of the graph of a function y=2x+4
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! find the distance between the x-intercept and y-intercept of the graph of a function y=2x+4
-----
x- intercept ?
Let y = 0; then solve for "x"::
2x+4 = 0
2x = -4
x = -2
--
x-intercept:: (-2,0)
=======================
y- intercept ?
Let x = 0; then solve for "y"::
y = 2*0+4
y = 4
---
y-intercept:: (0,4)
-----------
Your Problem::
distance = sqrt[2^2+4^2] = sqrt[20] = 2sqrt(5)
