Question 293300
Yellow trucking company for a round trip is 30$ and .10$ a mile after 250 miles
Cost = $30 + $0.10(x-250) where x is the number of round trip miles.
Plot two points and draw a line thru them:
If x = 250, y = 30
If x = 350, y = 40
Plot the points (250,30) and (350,40)
{{{graph(400,300,-10,400,-10,100,30+0.10(x-250))}}}
---------------------------------------
Gray trucking company for a round trip is 20$ and .10$ a mile.
Cost = $20 + $0.10x
If x = 100, y = 30
If x = 200, y = 40
Plot the points (100,30) and (200,40)
{{{graph(400,300,-10,400,-10,100,20+0.10x)}}}
------  
Putting both on the same axis you get:
{{{graph(400,300,-10,400,-10,100,30+0.1(x-250),20+0.1x)}}}
