How to the Equation Graph y = 3

In this video we'll draw the graph for y = 3. It is perhaps easiest to think of y=3 as being a line where all the values of y are 3. That means for any value of x, y will be 3. Because of this we end up with a horizontal line that crosses the y-axis at 4 and does not cross the x-axis. We could also use a table of values to plot points on the ...
