Question 549849
using the graphing method how do you do y=3, x+y=5 Please help me and how to do it.
-----
Graph y = 3 as a horizontal line passing thru all points where y = 3.
---
Solve x + y = 5 for "y":
y = -x+5
Plot two points:
(0,5) and (5,0)
Draw a line thru them.
--------------
Solution:
Find the point where y =3 meets y = -x+5
Answer: (2,3)
--------------------
Graph:
{{{graph(400,400,-10,10,-10,10,3, -x+5 )}}}
