Question 310452
Solve equation by graphing.
2x + y = 1
y = -2x + 5
-----------------
1st Equation:
Solve for "y":
y = -2x+1
Determine and plot two points:
Let x = 0, then y = 1 giving you point(0,1)
---
Let x = 1, then y = -2+1 = -1 giving you point (1.-1)
---
Plot the two points and draw a line thru them.
======================================================
2nd Equation:
y = -2x+5
Determine and plot two points:
Let x = 0, then y = 5 giving you point (0,5)
Let x = 1, then y = -2+5 = 3 giving you (1,3)
----
Plot the points and draw a line thru them.
======================================================
{{{graph(400,300,-10,10,-10,10,-2x+1,-2x+5)}}}
Find the point of intersection by inspection.
==========================
Answer: The lines are parallel so there is no solution
for the system of two equations.
