Question 163948: 3. Plot the graph of the equations 10x - 4y = 3 and 5x - 2y = 6 and interpret the result.

Plot the graph of the equations:
10x - 4y = 3
If x = 0, y = -3/4
If y = 0, x = 3/10
---------------------
Plot the points: (0,-3/4) and (3/10,0)
Draw a line thru them to get:
===============================
and 5x - 2y = 6 and interpret the result
Solve for "y":
y = (5/2)x-3
If x = 0, y=-3
If x = 2, y = 2
---------------------
Plot the points: (0,-3) and (2,2)
======================================
Find the point of intersection. The x/y values
of that point satisfy both equations.
=======================================
