graph the equation. y=-8x+2
----
Plot two points::
If x = 0, y = -8*0+2 = 2 giving you point (0,2)
If x = 1, y = -8(1)+2 = -6 giving you point (1,-6)
----
Plot the points and draw a line thru them::
slope = (-6-2)/(1-0) = -8
y-int = f(0) = 2
----
Equation:
y = -8x + 2

+y+=+8x+%2B+2+
---------------
All you need to plot is 2 points, since it's
a straight line
---------------
First, set +y+=+0+
+0+=+-8x+%2B+2+
+8x+=+2+
+x+=+1%2F4+
So, you have the point ( 1/4, 0 )
------------------------------
Then set +x+=+0+
+y+=+-8%2A0+%2B+2+
+y+=+2+
Now you have the point ( 0,2 )
------------------------------
Here's the plot:
