or here on Desmos to create a linear relation. Find the equation of the linear relation.
Fill in the table again and again to create as many different linear relations as you can.
What do the graphs have in common? What do the equations have in common?
y = 3x + 3
y = 1/2x + 3
y = 2x + 3
y = -2x + 3
The graphs all have the same y-intercept, and therefore have the same constant.
