Question 179476
Will you please advise if I'm on the right track. 
Plot the graph of the equations 2x-3y=5 and 4x-6y=21 and interpret the result. 
-----------------------
2x-3y=5
x-intercept: Let y = 0, then x = 5/2 giving you point (5/2,0)
---------------
yintercept: let x = 0, then y = -5/3 giving you point (0,-5/3)
---------------
Plot the two points and draw a line thru them to get:
{{{graph(400,300,-10,10,-10,10,(2/3)x - (5/3))}}}
---------------------------------------------------------
4x+6y = 21
x-intercept: Let y = 0, then x = 21/4 giving you point (21/4,0)
---------------
y-intercept: Let x = 0, then y = 21/6=7/2 giving you pont (0,7/2)
----------------
Plot the two points and draw a line thru them to get:
{{{graph(400,300,-10,10,-10,10,(-2/3)x +(7/2))}}}
