Question 610579: how do i graph linear equations? grahing is so difficult for me and I hate to see it when I'm doing trigenometry or something like that. Please teach me. how do you solve this question:
y=-2x+1
y=x-5
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
y=-2x+1
You need 2 points to determine the graph of a line.
Let x = 0, then y = -2*0+1 ; so y = 1
Point (0,1)
Let x = 2, then y = -2*2+1 = -4+1 = -3
Point (2,-3)
---
Plot the 2 points and draw a line thru them to get:

==========================================================
y=x-5
Let x = 0, then y = -5
Point (0,-5)
-----------------
Let x = 2, ten y = 2-5 = -3
Point (2,-3)
----
Plot the points and draw the graph thru them to get:
