**Goal**• Given a table of data, find an equation of the line in the y=mx+b form.**Step 1**Write original equation: y=mx+b**Step 2**• Find the slope. Pick two points and plug them into .**Step 3**• Plug the slope in for m into y=mx+b**Step 4**• Check to see if x=0 is a point. If so, that y-value is the y intercept. Plug that number in for b.**Step 5**• Of x=0 is NOT a point, then we must find b. Pick any point from the list and plug it in for x and y. Then solve for b. • Plug b into final equation.**Homework**• Back of in-class examples
