The line y=2x+1 can be written in the form (x, y) where y is a function of x. So to find two points on the line, we can pick two values for x and use the equation y=2x+1 to find the corresponding y values.
For example, let's choose x=0 and x=1:
When x=0, y = 2(0) + 1 = 1
So the point (0, 1) is on the line.
When x=1, y = 2(1) + 1 = 3
So the point (1, 3) is on the line.
So the two points on the line Morgan graphed are (0, 1) and (1, 3).
