What do we think the point of intersection is?
-2 points intersect each other
-On a graph when a line crosses the axis or another line.
-y-intercept, x-intercept
-2 lines cross each other
The point of intersections have the same coordinates.

Equations for finding slope and y-intercept
The class came to a conclusion...
Standard form
ax+by=c
slope= -a/b
y-intercept= c/b
***You cannot find slope and y-intercept until y is by itself
